I saw it on apple.com/downloads. It said it was really fun and entertaining, so I downloaded it, and made an account. I only started to play MP around Sep 08 though. Before that I was just messing around with some mods in SP...
I wanted a new Rag doll-physics game. Searched for one, found Toribash. Didn't appeal to me at first, but then I tried Multiplayer. That's when it started getting fun.
