Really awesome game; although not very realistic. If you enjoy designing and building your own creations then exploring around space and landing on planets/moons you will likely enjoy this game. However, the lack of compound blocks is a very big oversight on behalf of the developers and their statement the they will never be added to the game is more than a bit disappointing. Especially since their other game "Medieval Engineers" pretty much relies on them. This game could greatly benefit from them, at least for aesthetic reasons.
