Starbound

[kattiq]

I recently got this game on sale and it's actually really fun! Similar to Terraria's lay out if you've ever played that, but you can travel to different planets, have a spaceship and in general has a lot of really cool stuff in it- plus you can add mods to it.
Also multiplayer so you can play with friends- which would be great cause some of the mods on other planets are really hard to beat.
