The game is $10 right now on Steam. Stop pirating the game and buy it. It's a good game with a ton of mods. It's from 2012 and still getting updates this year so it's heavily supported. There is no reason to pirate this game. It's easily worth the $40 it normally costs even in 2017. It's well worth $10.
