Info about Sins of a Solar Empire II: Harbinger:

Official game description:
The Vasari have been running for nearly 10,000 years from the 'great threat' that destroyed their empire. For 35 years, they’ve warned anyone who would listen about it drawing near…. Now, they have arrived: the Eidolon.
The Eidolon don’t value typical assets like other races, but they do exploit them as a way to spread their corruption more effectively. They seek only to corrupt those they encounter, transforming them into something else to empower themselves.
**Features**
------------
*   **Planetary Transformation:** The Eidolon spread corruption across the galaxy to empower themselves and their worlds. As populations fall under the Eidolon’s influence, their planets gain corruption over time. Once a world has fully fallen, it can be shrouded, greatly expanding the upgrades that planet can support.
*   **Unit Corruption:** Corruption empowers Eidolon units in combat as well as weakens them. As an Eidolon ship gains corruption, its hull dwindles while its offensive power increases. Enemy forces can become infected by corruption, giving the Eidolon another advantage.
*   **Null Weapons:** Eidolon weapons are far more advanced than those of the other factions; and can negate shields and spread corruption against enemies.
*   **Cloaked Ships:** Subterfuge is one of the great enemy's sharpest weapons, as seen on the Kalizaeth Profaner support capital ship. New cloaking and detection systems let the Eidolon appear and vanish at will, enabling hit-and-run tactics that reward patience and punish anyone caught off guard.
*   **Psionic Abilities:** The Eidolon possess psionic abilities that allow them to seize control of lesser beings and drive Vasari ships into madness, firing on friend and foe alike.
*   **Phase Echoes:** Sometimes the dead don't die. Eidolon units infused with corruption may refuse to die and carry on the onslaught.  
*   **Discover** more about the Sins universe as you explore ancient technology and research new Eidolon capabilities.

Feature scans:
- MTX: score 15; verdict: Fair / Traditional DLC - Not Predatory; summary: The reviews focus on the price and content value of a traditional faction DLC, plus premium-edition and content-pass bundling. There is no direct evidence of real-money gacha, loot boxes, in-game currency obfuscation, paid power, or a post-purchase cash shop. One review explicitly praises the absence of pay-to-win design, and another notes shared DLC access. Under the audit rules, traditional DLC and base-price complaints cannot push the score above 20.
- Proton/Linux: score 15; verdict: Works Well; summary: The available Linux/Proton feedback is uniformly positive. Users report the game and DLC run smoothly on a Debian-based Linux system using Steam and Proton GE, with no Linux-specific launch failures, crashes, anti-cheat blockers, or workaround-heavy setup. The only caveat is that Linux is not officially supported.

- Hardware Profile: No data
Feature extractions:
- Community Price:
  - Community fair range: $20.00 - $30.00
  - Reasoning: Direct base-game price evidence is sparse because most reviews discuss DLC value. The base game is described as okayish, and its factions are said to have more content than the criticized DLC, suggesting the base game itself is not viewed as badly overpriced. General price sensitivity and positive value comparisons imply a fair base-game range below the current $29.99 ceiling, roughly $20-$30, with $20 reflecting discount expectations and $30 the current upper bound. Confidence is limited because the reviews do not directly price the base game.
- Playtime Metrics:
  - Game completion: 200.0h
  - Story completion: N/A
  - Session length: 1.0h
  - Endgame: N/A
  - Reasoning: The '200+ hours' quote is the only explicit numeric total playtime tied to playing the DLC faction, so it is used as a lower-bound game completion/experience estimate. The '100% completed' quote confirms achievement completion but gives no hours, so it does not refine the number. A translated Chinese review reports a one-hour trial session, supporting sessionLength = 1 hour. No review provides hours for story completion or endgame, so those metrics remain null.
- Time-to-fun:
  - Summary: The faction is widely described as a slow, resource-starved, and often tedious early experience that becomes fun once it gets rolling or builds a web of propagation. Some players enjoy it within the first hour, but the dominant profile is clicks after.
  - Stance: Clicks after
  - Anchor: Getting the faction rolling or establishing a web of propagation
  - Time to anchor: N/A
  - Friction: Very slow and boring early game; Early resource starvation and slow economy; Tedious corruption and shrouding busywork; Corruption generation and shrouding take too long; Sharp learning curve versus Vasari mobility; Poor early-game survivability in skilled PvP
  - Unlock drivers: Getting the faction rolling; Creating a web of propagation; Stronger ships than other factions; Mid/late-game fleet corruption reduces corruption drawbacks; Dark theme song/immersion helps the faction grow on the player
  - Conditions: If player can tolerate the extremely slow and boring early game; Playing PvE, where stronger ships make them very strong early; Playing multiplayer, where winning requires bringing your A-game; Prior experience with Vasari hit-and-run mobility; Whether planets are shrouded, since unshrouded planets hurt early economy; Establishing a web of propagation; Mid-to-late game corruption amount from the fleet
- Player Archetypes:

- Voice acting on ships good (weight 0.08): The voice acting on ships is really good. It adds to the overall experience.

Common complaints:
- DLC Overpriced and Poor Value (weight 0.86): Many players feel the DLC is significantly overpriced, especially at $30, and does not offer enough content or value for the cost. The price is considered too high for what is essentially one faction with limited features.
- Corruption Mechanic Underwhelming (weight 0.59): The corruption mechanic is criticized for being poorly balanced, lacking counterplay, and not engaging. It often feels like micromanagement hell and slows down gameplay without meaningful impact.
- Missing Command Ships (weight 0.44): The new faction lacks command ships that other factions have, which is a major oversight. Some players note that command ships are scheduled for later but should have been included at launch.
- DLC Unfinished and Rushed (weight 0.37): The DLC is widely described as unfinished, feeling like an early beta or rushed product. It lacks polish and completeness, with missing features and balancing issues.
- Tech Tree Barebones and Uninspired (weight 0.32): The tech tree for the new faction is considered thin, with few unique or interesting upgrades. It lacks depth, uses placeholder images, and has many duplicate or copied elements.
- Faction Feels Incomplete (weight 0.25): The new faction is seen as unfinished, lacking options and depth compared to older factions. It feels like a concept rather than a fully realized addition.
- Only One Faction Variant (weight 0.22): Unlike other races that have two faction variants, the new race only has one, reducing variety and replayability. This is a common disappointment among players.
- Balance Issues with New Faction (weight 0.14): The new faction is considered either too powerful or unbalanced, throwing off game balance. A balance pass is needed to address these issues.
- Missing Super Weapon (weight 0.12): The faction lacks a super weapon, which is a notable omission compared to other factions. Players expect a powerful, game-changing super weapon.
- Stealth Mechanics Useless (weight 0.08): Stealth mechanics are considered unnecessary and ineffective, adding little to gameplay. They are often ignored or seen as a wasted feature.
- Economy Slower Than Usual (weight 0.08): The economy feels sluggish and slower than in previous games, impacting the overall pace. This can make early game progression feel tedious.
- Planet Development Monotonous (weight 0.08): Planet development lacks variety, with little difference between planets. The process feels repetitive and all planets follow the same development path.
- Galaxy Map Visual Clutter (weight 0.08): Corruption spread lines make the galaxy map visually noisy and hard to read. This obscures important information like phase lines.
- Ship Models Hard to Read (weight 0.08): Ship model parts such as hangars and turrets are not clearly visible, making it difficult to distinguish hull from weapons. This affects visual clarity in combat.
- Unique Currency Missing (weight 0.08): The alien race uses credits instead of a unique corruption-based currency, which reduces faction identity. Players expected a distinct resource system.

Gameplay feedback:
- Corruption core mechanic (weight 0.74): A corruption system is central to the new faction, allowing players to spread corruption to planets and enemy empires, and use it to fuel abilities. It grants bonuses and maluses, and can be managed strategically.
- New fourth faction added (weight 0.68): The DLC introduces a fully playable fourth faction, known as the Harbinger or Eidolon, which is the first brand new faction in the game. This faction brings unique mechanics and playstyle.
- Faction unique mechanics and playstyle (weight 0.55): The new faction plays completely differently from the previous three, featuring stealth, corruption, and shrouding mechanics. It has unique research, ships, and abilities that distinguish it.
- Shrouding planets mechanic (weight 0.39): Players can corrupt planets and then shroud them, unlocking strong bonuses and development slots. Shrouding requires filling a corruption meter and spending resources, and it can permanently alter the map.
- Stealth and cloaking abilities (weight 0.37): The faction utilizes stealth mechanics, with some ships capable of cloaking, including a titan with perfect cloaking. However, cloaked ships sacrifice combat effectiveness and can be detected.
- Eidolon ship corruption effects (weight 0.34): Eidolon ships gain high damage and regeneration buffs from corruption but suffer hull decay, especially at full corruption where hull degrades to 25% and regeneration stops. This creates a risk-reward mechanic.
- Faction variety and uniqueness (weight 0.25): The game features multiple factions with unique titans, research, and ship designs. The new race is stat-focused and has high damage output.
- Corruption spread and management (weight 0.24): Corruption can be spread from asteroids to connected planets, but it does not affect enemy planets or link between planets and fleets. Managing corruption requires monitoring and spending for buffs.
- Eidolon race details (weight 0.23): The Eidolon race is a playable faction with heavier ships and weapons, high DPS, and resilience. They are an invasion-style faction.
- Corruption debuffs enemies (weight 0.2): Corruption applies debuffs to enemy ships and planets, such as reducing TEC gun range and detection range, and adding time to Vasari phase jumps. It forces other factions to go on the offensive.
- Faction lacks command ship (weight 0.19): The new faction does not have a command ship or dreadnought, relying instead on a titan. This is a notable limitation compared to other factions.
- Economy and tech tree issues (weight 0.19): The starting economy is weak and slower than usual, and the tech tree feels barebones or thin. These factors can hinder early game progression.
- Only one faction per race (weight 0.13): The new race has only one faction, unlike other races which have two. This limits variety for players who prefer multiple sub-factions.
- Corruption generation by ships (weight 0.13): Only select ships generate corruption, such as a capital ship that can give the entire fleet corruption, or a support ship that corrupts one ship at a time.
- Corruption as fleetwide stat (weight 0.08): Corruption is a fleetwide stat that provides buffs at low levels but damages ships at high levels. It requires monitoring and spending to manage effectively.
- Ships arrive via portals (weight 0.07): The faction's ships arrive through portals, which is a unique method of deployment. This adds to the faction's distinct feel.
- Warp starbase issue (weight 0.06): The warp starbase cannot move and moves away from the star after warping, making it useless. This is a specific bug or design flaw.

Performance notes:
- Purple lines cause FPS drops (weight 0.09): Players lose around 20 FPS when zooming out in late game due to purple lines from the propagate ability. FPS also drops when zoomed in on a planet or ship because of these lines.

Recommendations:
- Recommended for fans (weight 0.41): Fans of the base game, 4X, RTS, or sci-fi/fantasy genres often recommend the DLC. They appreciate the new faction and lore additions.
- Wait for sale (weight 0.36): A common recommendation is to wait for a discount, often 25-50% off, before purchasing. Some suggest waiting until more content is added or the faction is finished.
- Unfinished and buggy state (weight 0.28): Reviewers criticize the DLC for feeling unfinished, with missing features like rebel forces and dreadnoughts, and bugs such as starbase and mobility issues. They recommend waiting for patches.
- Mixed or soft recommendations (weight 0.22): Some reviewers give soft recommendations, acknowledging the DLC's potential but noting it's not a must-have. They suggest buying only with a discount or if you already own it through a bundle.
- Good for experienced players (weight 0.14): The DLC is recommended for veteran players who want a challenge and are willing to master the new faction. It is not advised for beginners.
- New faction underpowered (weight 0.12): The new race is considered weak in PvP and not fun for players seeking strength. Some refuse to play with or against it.
- Price should be lower (weight 0.05): Reviewers suggest the DLC should be priced around $15 or less, and that the current price is too high for one faction.
- Visual and sensory appeal (weight 0.05): Some players find the DLC visually impressive and worth buying for the sensory experience, even if gameplay is lacking.
- Avoid bundle, stick to other DLCs (weight 0.05): Some advise against buying the bundle and instead purchasing other DLCs that offer better value.
- Multiplayer cost sharing (weight 0.04): Only the host needs the DLC, so groups can pool funds to buy one copy and share it.
- High-end PC required (weight 0.04): The expansion is recommended only for players with powerful PCs to handle its demands.

Other player notes:
- DLC Price Is $30 (weight 0.29): Multiple reviewers explicitly state the DLC costs $30 USD, which is over half the base game's price. This price point is a frequent point of contention.
- Eidolon Faction Added (weight 0.25): The new race added by the DLC is the Eidolon, which becomes the fourth faction in the game. Some reviewers note it only has one faction at release instead of the usual two.
- DLC Adds New Race (weight 0.21): The DLC introduces an entirely new playable race to the game. This is a major selling point and a key feature highlighted by reviewers.
- Future Content Planned (weight 0.14): Reviewers mention that more updates, patches, and DLC are confirmed to be coming in the future. This includes additional content for the game.
- Command Ships Coming 2026 (weight 0.14): Command ships for the Eidolon faction are planned for an update in October or September 2026. This indicates post-launch support.
- Shared DLC Access (weight 0.09): If one player owns the DLC, others in a multiplayer session can access the content as long as the host has it. This mitigates the cost for some players.
- Reinforcements DLC Command Ships (weight 0.08): The Reinforcements DLC adds command ships for base game factions. This provides additional units for existing factions.
- DLC Included In Content Pass (weight 0.07): Some reviewers obtained the DLC as part of a Content Pass. This affects their perceived value of the purchase.
- AI Generated Art Used (weight 0.07): The game uses AI-generated art, which some reviewers note as a point of concern or criticism. This may affect the game's reception.

Emotions:
- Disappointment (weight 0.23): Players are deeply disappointed by the unfinished state of the new Eidolon faction, which lacks a command ship, dreadnought, and multiple sub-factions compared to other races. The high price of the DLC does not match the thin content, with missing features like superweapons, unique victory conditions, and placeholder tech tree art. The faction's corruption mechanic feels underwhelming and unbalanced, and the visual design appears lazy or reskinned from existing races.
- Frustration (weight 0.16): Frustration stems from the faction's slow, clunky design and severe balance issues, including overpowered units that were quickly nerfed, making early game transitions impossible. The corruption mechanic is punishing with no counterplay, requiring constant micromanagement and causing permanent planetary debuffs. Additionally, promised features like a campaign are missing, and the high price for an incomplete faction feels like customers are being used as beta testers.
- Excitement (weight 0.09): Excitement is driven by the long-awaited arrival of the fourth faction, the Eidolon, and their unique corruption and shrouding mechanics that add a new strategic layer. Players enjoy the fresh gameplay, powerful units, and the revelation of the mysterious enemy that chased the Vasari. The faction's alien feel and the ability to turn the map against opponents create a strong sense of anticipation and novelty.
- Enjoyment (weight 0.07): Players find enjoyment in the Eidolon's distinct playstyle, which offers a new and fun experience compared to other factions. The corruption mechanic allows for strategic economic warfare, and the shrouding system with different planet abilities adds depth. Despite pricing concerns, the faction brings fresh content and engaging combat that keeps the game fun.
- Satisfaction (weight 0.06): Satisfaction comes from the Eidolon faction feeling balanced yet powerful, with innovative mechanics that fit well within the game's lore. The art style, music, and sound effects are praised, and the faction delivers on nearly 20 years of anticipation. Players appreciate that the corruption mechanic is versatile and the DLC feels worth the price for those who bought the content pass.
- Dissatisfaction (weight 0.04): Dissatisfaction is caused by the DLC feeling half-finished, with missing features like a command ship and too few technologies for the price. The corruption mechanic lacks counterplay and feels like tedious busy work, while the overall gameplay experience is unsatisfying due to simple mechanics and unclear weapon projectiles.
- Annoyance (weight 0.04): Annoyance arises from poorly designed cloaking mechanics that are ineffective and annoying to use in mixed fleets, as well as the corruption mechanic breaking the game's flow and requiring excessive micromanagement. Voice lines are considered goofy rather than intimidating, and minor UI issues like a tiny tech tree art thumbnail further irritate players.
- Appreciation (weight 0.04): Appreciation is expressed for Stardock's continued support and expertise in niche 4X/RTS games, as well as the new faction's unique mechanics and visual design. Players value the developer's clear passion and the strategic depth added by the corruption mechanic, which enhances the overall gameplay experience.
- Hope (weight 0.02): Hope persists that the developers will deliver on promised content, including future races and improvements, based on their track record of free updates and reworks. Players look forward to more content after the current pass and believe the game will continue to grow.
- Love (weight 0.02): Players love the Eidolon faction for its distinct feel, intimidating presence, and the evident love Stardock poured into its design. Despite initial surprise, the new race is considered great and worth the long wait, with visuals and mechanics that resonate strongly.
- Boredom (weight 0.02): Boredom sets in due to the Harbinger faction's extremely slow and boring early game, with planetary corruption mechanics that quickly become repetitive. The faction relies purely on numbers, reducing the role of interesting mechanics, and the tech tree and planet items feel bland.
- Anticipation (weight 0.02): Anticipation is high for the upcoming command ship promised by the developers, as well as future races and patches. Players are looking forward to how the DLC will be improved over the next few months and how the game will continue to evolve.
- Surprise (weight 0.01): Surprise stems from the revelation that the Eidolon are not the alien swarm expected, but rather something related to Unity, which subverted player expectations for a more tyranid-like enemy. This twist in the faction's true nature caught many off guard.
- Concern (weight 0.01): Concern is raised about multiplayer balance, as the Eidolon's massive ship durability and powerful abilities may make them a prime target and cause other races to struggle. This could lead to a frustrating experience for both Eidolon players and their opponents.
- Optimism (weight 0.01): Optimism is fueled by the developers' receptiveness to feedback and active engagement with the community. Players believe that critiques are being addressed and that balance improvements will continue, leading to a better game overall.
- Anger (weight 0.01): Anger is directed at publishers' treatment of customers, including price gouging and reliance on AI art, as well as the rapid nerfing of the new faction DLC within a week of release. Developers' low productivity and lack of understanding further fuel this anger.
- Disgust (weight 0.01): Disgust is provoked by ship visuals that are busy, flat, and physically hard to look at, as well as a mechanic that feels disgusting for both the player and the opponent. The overall aesthetic and design choices repel some players.
- Happiness (weight 0.01): Happiness comes from the addition of a fourth unique race, the Eidolon, and the effort put into its development. Players who supported the game are pleased with the new faction, especially those who obtained it through the premium edition.
- Confusion (weight 0.01): Confusion arises from not understanding the negativity toward the DLC, as well as the corruption mechanic being poorly explained and impossible to keep track of. This lack of clarity hinders enjoyment and comprehension of the new systems.
- Admiration (weight 0.01): Admiration is felt for the Eidolon as a genuinely unique and interesting faction, with distinctive ship models and evident developer effort. Players enjoy examining the ships, animations, upgrades, and descriptions in detail.}
