I'm totally down for playing like anything. I like to play different things, hard for me to commit to one game. But, this site looks promising, heres a list of the pc games they have leagues for, http://gamebattles.com/pc/

To bad not many have l4d, if we get 3 people with it other than me i'd totally be down for doing a 4sf team for it. TF2 would be fun, and and and, 1.6 is on there ^_^

I want to play some...

Quake 1, 2, 3 (always quake :D )
UT1
Broodwar(entropy too)
BATTLEFIELD 1942 and VIETNAM
TF2
Dawn of War: Soulstorm
Half life 2 Jaykin bacon source <-- super fun
Sven Coop
the battlegrounds 2
fistful of frags
old multiplayer games in general
