I just play CounterStrike(1.5.....none of that Steam/1.6 crap.). Thing is, it's hard to set up a "lets meet up on there and play" type thing. You'd have to have the ip to a certain server and stuff, then if the server is far away from your friend you want to play, they will lag bad, etc.
But yeah, if anyone here has CS and wants to play, feel free to pm me. I'm up playing in the wee hours of the morning, so you'd have to be up around then. Or in a different time zone.
