I will not evaluate, just because my opinion is divided. On the one hand the fact of being able to walk around in his ship/planet is just cool but for the rest the game is empty !

This games is just huge, me who loves games in space, driving my scientific vehicle on Martian soil is a sensation that I do not find in any games.

Well what about this game? Well just that it is excellent! You have an infinite possibility of creating things, tons of addons and all that for how much? $9.99
