Kerbal Space Program 1.0 Released After 4 Years of Development
hampton2600 writes: The beloved space simulator game Kerbal Space Program has just hit version 1.0 after four years in development. It has risen to prominence in public beta, but the full release brings a host of new features: "The flight model has had a complete overhaul, meaning the lift is now calculated correctly to all lift-generating parts, which includes lifting bodies. The drag simulation has also been completely revised, and uses automatically pre-calculated data based on the each part’s geometry, to be finally applied based on not just the orientation of parts in flight, but also taking other parts into consideration. ... A new heating simulation has been implemented together with the improved aerodynamics. Now, not only temperature but also energy flux is considered when making heat calculations, meaning radiative, conductive, and convective heating and cooling are all simulated and all parts have their individual thermal properties. Parts will emit a blackbody radiation glow if they get hot enough." To the mun!
The Steam version is also DRM free; Steam is just used as a downloader. Once downloaded you can move it to another directory or even another computer, and even uninstall Steam.
You could always buy directly from Squad as well and just download a ZIP file.
KSP has never had DRM.
