Favorite Personal Computer Game

My favorite computer game is Unreal Tournament 2004. It is a first person shooter with plenty of destructive armament and proportional gore. The 2004 version is the sequel to UT2003, and is a continuation of a long line of the Unreal franchise; which includes Unreal, Unreal II, Unreal Championship, and the Unreal Tournament series. Unreal is developed cooperatively by Epic Games and Digital Extremes. The various iterations of the Unreal game engine are practical and versitile platforms, and are used under lease in various titles, most notably the Tom Clancy's Rainbow Six Vegas series.
