Well, that's sorta the point. It's NOT Empire Terraria so advertising another game is not "illegal". If it was. The Jupiter Squad would not exist. http://empireminecraft.com/threads/the-jupiter-squad.30538/
I'm sad...don't have the real version...computer with steam installed is dead...and I can't get the on sale version. Still. I'll be happy to watch videos if you can make them.
I didn't bring it up illegally... I didn't insult Minecraft, either. I'm just saying it has no objectives other than build and survive. And those aren't fun.
