Quakelive would be a very fun tournament.
Quake Live would be great but no LAN support.
Could always do Quake 3.
I would like to run a "for fun" 1v1 Warsow tournament. Warsow (
www.warsow.net) is free to play and is just like Quake 3 but with updated graphics, the ability to wall jump and LAN support.
I have ran previous tournaments and from people that love Quake I have gotten nothing but good feedback. Here are videos from the grand finals of our first Warsow tournament:

I fond this on another topic... I'll have to check it out tonight and i might change my response, although i'd rather have a small team even if it's just 3v3 than a 1v1...
