Buy Kerbal Space Program

Kerbal Space Program is a video game in which you must construct a spacecraft capable of flying into space with its crew, without killing them in the process. The player has an immense amount of parts to build a fully functional ship. Each of these parts has a function, so whether your ship flies or not will depend on how the ship is constructed and with which parts. If you're interested in rocket science at all, Kerbal Space Program is a perfect game to dabble around and learn something about it at the same time. The three gameplay modes available are Sandbox, the mode where you have the option to build whatever you want to, Science Mode, where you can perform various scientific experiments to further improve your knowledge and technology of Kerbalkind, and finally Career Mode, which makes you manage every aspect of your very own Space Program, so you will take care of administration strategies, Crew Management, Reputation, and you will take up Contracts to earn Funds which will help you upgrade your Space Center Facilities or repair them. Done in collaboration with NASA, Kerbal Space Program features an ability to capture asteroids, mining for resources will also be one of your jobs, and of course, building Bases and Space Stations. Using the Vehicle Assembly Building and the Space Plane Hangar the player is able to build a spacecraft of his choosing with tons of combination parts at their disposal. Everything will fly and crash realistically thanks to the physics based Space Flight Simulator. There's even an option to take out the Kerbal crew out of their ships to do Extra Vehicular Activities. Visiting the Moon and other planets is something that the player will be aiming for. The Kerbal Planet is 600km in radius and it's procedurally generated thanks to Procedural Terrain. Ship systems in Kerbal Space Program are very delicate, so watch for engine temperatures and even fuel levels so your ship doesn't explode. Space Kerbal Program is definitely one of the best, if not THE best space simulator game out there, with immense depth and complicated, but rewarding gameplay.
