There is a new game on Steam that is still in it's alpha stages(early access) but is already an amazing game. It's like a combination of Space Engineers and No Man's Sky but much better than both. 11 planets to land on, creativity to build what ever you want and a complex survival mode; what more could you want from the game?
The Community is already involved tonnes with nearly every Star Wars creation.
I bought it myself and just love how much freedom it gives.
Go check it out(are we allowed to post links?)
