What do our users think of Kerbal Space Program for PC Digital?
the mission are really fun and al but to be honest i spend most of my time in sandbox mode trying to make the longest rocket possible go into orbit, as well as a ton of other people out there so if you like playing wiht physics and space then this is definitly a game for you.
An awesome game. Spent many hours building vehicles (both air and space). The art style is cool and the physics system is good. Reaching different planets can be pretty challenging.
Great game, is especially nice for people who really like space travel and space stations! You can customize and make almost everything! From moon bases to interstellar space shuttles (with mods)
A very nice and scientific true game, but if you don;t like to play with physics (like me) then don't buy it!
This is an awesome game at 0.25 already. It taught me more about ballistic trajectories, rocket science, orbits and space in general that I would have never known. Also it's great fun just building stuff and seeing wether it'll fly or not. A must have!
