Unreal Tournament is a first person shooter (fps). Usually, in that genre, for online gameplay, there are 3 games you have to choose from for the most bang for the buck; Half Life, Quake 3, and Unreal Tournament. Half life is supposed to be the ultimate, though I've never played it. I can say from personal experience that I thought Quake 3 really blew (the only reason being the game play, it didn't "feel" too good playing). Unreal Tourney, while not the most graphically fantastic (though the graphics are quite Unreal... stupid pun, let it go), many people agree that it is the ULTIMATE in terms of gameplay. Give the demo a shot PC, I played the demo for about a year before upgrading to full version, and I never got tired of it! Also, this should be said, Quake 3 and Unreal Tourney are multiplayer deathmatch style games. Theres no one player adventure style, its all deathmatch style. Half Life supposedly has THE supreme one player game fps ever.
