Gmod 10

My brother and I are getting a game called Gmod 10 (Garry's mod 10) today. Gmod is a "physics sandbox" game. This means you can do just about anything. If somebody is annoying you then you can trap him under a dumpster for a while. You can also spawn game A.I.s to bother people, help you out or just look like a dork. This sounds like an awesome, awesome game and I hope to start ASAP. I don't even know what I'll do first because I'm so excited! Gmod 10, here I come!
