Also, Minecraft.
It may be possible to set up a server for us all to get into and play together on. Minecraft costs about $20

Hey, I was looking into some games we could all play together.
All these are on steam for free

--Alien Swarm - Top down shoot em' up by Valve - Free

--Team Fortress - Teamplay and objective based game - Free
http://www.youtube.com/watch?v=ZN6BwUKQ0sA#t=1m37s

--Super Monday Night Combat - Not sure about this one cause I have no idea what it is but is free on steam

Tribes Ascend - Teamplay and objective based skiing/shooting game

--Microsoft Flight Simulator. Free on steam the only drawback is that it is Microsoft Flight Simualtor.

All of these are shooting games which can get a little repetitive after while.
Gumboy Tournament is pretty cool, we can play with 9 people and capture the flag and race and do other objectives and costs $3

Ideas anyone?

If anyone is looking for an awesome game, Tribes: Ascend is a great shooter and its on Steam and its free! Think Doom/Unreal Tournament but with cross country rocketskiing to the enemy base.

Haha! Raatbagh. Yeah!

Perhaps we should have some sort of games/tournament night if we could agree on a game? I couldn't help but notice that Recreational Activities at Burton and Garran Hall has 0 upcoming events in the next 2 weeks

RAatBaGH, I like it, it's catchy
