Starmade is basically multiplayer Minecraft, except in space (SPAAAAAAAAAAACE). You make spaceships and space stations, to either fight other players, or the computer.
The game is in early alpha right now, so it is very buggy. But it is free (for now at least, the full version won't be), so you can't really complain!
