I do have UT, though and I can pull together 3 or four others who would link up, all with high bandwidth connections. One of them is an avowed democrat though, but like the rest, he can be a lot of fun to shoot, too.
I'd recommend MOH is you haven't played. The Normandy Landing level is right out of "Private Ryan". Get the patch and the "blood pack" mod from www.planetmedalofhonor.com. Lots of Nazi-killing goodness to be enjoyed here.
Jedi Knight II has very similar game-play to it's predecessors. Lots of puzzles coupled with tons of battles with Storm Troopers and Light-Saber wielding sociopaths. It became A LOT OF FUN when I found the cheat codes that activated realistic light-saber combat ("Helpusobi 1" in the console followed by "g_saberrealisticcombat 1"). VERY GRUESOME. I never laughed so hard. It took about 3 seconds to fall to the "Dark Side" after that. Luke would have been pissed.
Anyway, Freepmail me when you have the server up and going.
