Madd and I have been building crap in a space engineers private server for a bit and probably could use a change. My megagrinder ship has made things interesting.
It's a big manouverable plane of grinders. I capture NPC ships and then fly them into the grinder plane and it turns them into usable parts :)
can't garantee we'll be playing much minecraft either because there too many other games to play!
Do enjoy the build up to tech though quite a bit in tekkit.
