Hello! I have played Kerbal Space Program on steam for 80 hours, and it is one of the best games that I have ever played, I started out by messing around with random stuff in the game for the first 48 hours, but than I really started to get into career mode! TO ALL OF THE NEW PLAYERS! If you are considering getting into KSP, you should really start in career mode, it gives you a chance to learn the game and get fimiliar with parts, also Career is the most complete version of the game, as well, there is a lot more to do in carrer mode. KSP has really great mechanics and a great learning system, you can even take a tutorial when the game boots up! There are a lot of things that you can do in KSP, including. Make spaceships and Planes, Explore sites on planets, (including the starting one), Go into space, go into orbit around planets, go to both moons, go to all of the planets in the game, create planet bases, create space stations, create sapce planes, AND if you somehow get bored of all of that, than there are even MODS! It is a great game, and I reccomend it to anyone that wants a good challenge and light hearted game!
