It is a fantastic game, a bit shallow gameplay-wise in the long run but still hundreds of hours of fun if you make it past the learning curve. Very well made, and most impressively it models the entire Milky Way galaxy in full 3D, every star system has X number of stars and every system has X number of planets and each planet has X number of moons. And you can visit every one of them. You can even land on rocky planets and moons without atmospheres, and drive around in a SRV.
