I'm playing Ghost Recon: Desert Seige which IMHO on multiplayer is a great game.
Especially since I've installed the Asus ISDN card, the conenction is great now that I'm not using USB to conenct to BT's HH.
Still Quake 3. Seen no other game like it since. Loads of REALLY skilled players out there as well (and I thought I was l33t!)!!
I am looking forward to UT2003 though...
