Little green people who's sole focus in life seems to be based around launching rockets, crashing rockets and experimenting with, in and around said rockets. These little green people are the Kerbals from planet Kerban. In this world you are the lead of the Kerbal Space Program, designing both rockets and planes. Working against the very forces of all physics, you can slowly expand your project a few thousand meters up into the atmosphere, experiencing both the thrill and challenge of experimenting with aeronautics and rocketry, fine tuning propulsion systems and aerodynamics, slowly perfecting your craft in the art of hurtling little green men in pods into sub-orbit, full orbit, the Mun (yes, the Mun) and various other planets. A fun game which requires little skill at first to understand the basics, but presents a unique challenge to perfect those skills and successfully launch Kerbans, satellites, space stations and more around the local cluster of planets in a fully explorable solar system. Going on interplanetary missions to scout the surface of alien heavenly bodies, perform experiments in quite a number of ways in orbit, sub-orbit and on the surface of alien worlds. You can find out more about the Kerbal Space program here on their official website and here on the official Reddit page. If you like experimenting and the thrill of propelling yourself into space (and crashing numerous times) then this game is certainly worth looking into! Still receiving occasional updates which have made wonderful changes to the game, adding in sandbox, science and career modes to further expand on the challenges and possibilities.
