In Kerbal Space Program, take charge of the space program for the alien race known as the Kerbals. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics. Launch your Kerbal crew into orbit and beyond (while keeping them alive) to explore moons and planets in the Kerbol solar system, constructing bases and space stations to expand the reach of your expedition.
A great game but not the best port that we've seen due it's awful controls and the lack of modding on the console versions.
If you want to go where no Kerbal has gone before, at a rate faster than our own Earthly space programs, I would put Kerbal Space Program at the top of your list. Get stuck in to the breath-taking beauty of space, and take all the screenshots.
Kerbal Space Program more than a game is a hobby apart: a product that will push you to visit forums and not video games, to be interested in stars, zero gravity maneuvers, programming, aerodynamics and logic. Unmissable.
One thing should be noted: you will fail, and then fail some more.
Kerbal Space Program is a rare game, an unbelievably good simulator that unfortunately suffers from a being a fairly poor port from PC to console.
