The game is based on real science, and lets you explore the fictitious Kerbal Planet, as well as its surrounding moons, planets, and galaxies.
You can also learn how to build spaceflight systems, and eventually even space stations, starships, or surface bases on other planets.
It pretty much makes your dreams of being a NASA engineer, astronaut, or just a bad-ass space explorer, come to life.
Garnering impressive reviews from IGN, Metacritic and PC World, Kerbal Space Program is definitely a game to check out if you've ever dreamt of exploring the stars.
