Starbound

Basically its like Terraria but with space and planets with a level of awesomeness multiplied by one thousand. Its not protected by VAC so its impossible to get banned on it. Getting hacks on it is very easy and even without hacks the game is super fun and I just can't stop playing it
If you are into games like Terraria or Minecraft I highly suggest you check it out!

This is a really awesome game, I think it will be getting it's own section soon.

It's an aweome game but sadly in the beta phase there will be constant character erase before they start implementing a save or it's full release.
