I've been playing Unreal Tournament since about 2004 but I haven't been playing it online for the first year. At the moment I mostly play Capture the Flag online and Single player missions including the original Unreal pack with OldSkool amp'd. Things that I like of Unreal Tournament are the easy ways to make your own content, the diversity in weapons which makes them usefull in different situations and the freedom of movement (z-axis, dodge, dodging up ramps, air control) that the game gives you. The single player missions are most often a nice adventure in a good looking environment with a couple of surprises now and then.

Regarding the content of the wiki I'm currently planning to add some info to the Capture the Flag Maps for Unreal Tournament, some extra information on the Enforcer, the Dispersion Pistol Powerups and probably Seeds (Growing your own health is just too cool to neglect!)
