For me, I'd definately say it is UT2004.
I've played this game since the demo came out in early 2004, going on 4 1/2 years now. I play nearly every week, for several hours a week still. I've been in clans and been server admins for the game and it still never gets old.
I've got about 30 gigs worth of game files including custom maps, mutators, mods and total conversions. In addition to the original single player and multiplayer gameplay, to name just a few of the mods I can play: racing games, wacky tournaments, adventure games, side scroller and top down shooters, zombie shooters, realistic WWII shooter, tower defense, and even battle with cannons and airships.
All this and more for about $33.00. Best money I've ever spent on a game.
