This is one game that I really think should be on the play list! Basically its a moddification for both GTA Vice City, and GTA3 that allows online and LAN play. I have been playing this since the early stages, and although there are still several bugs, it is an amazingly enjoyble game. It is just like the single player, as in there are no rules, just simple death match, but with a bit of organising, you could arange a race, a CTF (or Capture the Whoopie Van) gametype. I really recomend you give this a look.

Just thought of a problem...Xfire doesn't support this, but ASE does, and there are a list of servers here.
