Info about Kerbal Space Program:

Official game description:
In **Kerbal Space Program**, take charge of the space program for the alien race known as the Kerbals. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics. Launch your Kerbal crew into orbit and beyond (while keeping them alive) to explore moons and planets in the Kerbol solar system, constructing bases and space stations to expand the reach of your expedition.  
Kerbal Space Program features three gameplay modes. In Science Mode, perform space experiments to unlock new technology and advance the knowledge of Kerbalkind. In Career Mode, oversee every aspect of the space program, including construction, strategy, funding, upgrades, and more. In Sandbox, you are free to build any spacecraft you can think of, with all parts and technology in the game.
Key Features

Feature scans:
- MTX: score 20; verdict: Fair with Concerns; summary: The user feedback for *Kerbal Space Program* reveals a mixed but largely positive perspective on its monetization model. While the base game and its DLCs are generally viewed as fair and optional, with no evidence of microtransactions or predatory practices, there is significant criticism directed at the sequel for being a 'cash grab.' Users also express frustration that certain gameplay features are locked behind DLCs, though this is not framed as predatory. The most severe concerns revolve around the perceived abandonment of the first game in favor of monetizing the sequel, which has eroded trust in the franchise's development priorities.
- Wiki: score 50; verdict: External Data Dependency (Instructional); summary: The primary issue identified in the user feedback is the heavy reliance on external resources (Wikis, YouTube, mods) to understand and progress in the game. While the in-game tutorial and documentation are insufficient, users are forced to seek guidance outside the game, which disrupts immersion and accessibility. Technical issues and mod dependency further exacerbate this problem. However, strong localization efforts, such as those in Japanese, are highlighted as a positive step toward mitigating these issues.
- Steam Deck: score 70; verdict: Tinkering Required (High Friction); summary: Kerbal Space Program (KSP) on Steam Deck presents a mixed experience. While the game offers deep, rewarding gameplay with realistic physics and affordability, it suffers from significant technical barriers. Users report frequent crashes, performance issues, and mandatory Proton workarounds, which violate the 'Seamless' criteria. Controller support is inadequate, often requiring external peripherals, and modding is overly complex, leading to instability. These issues create high friction, despite the game's strengths in simulation and creativity.
