Actually the game is a worthy sequel to the venerable UT99 (or UT1, or Original UT)
However while the game isn't better aside of the nice vehicular games and new game mods which some of them came out straight from UT mods like the bombing run and some game modes like assault who disappeared from UT2003 to do a come back in this title.
The game was made with a more competitive spirit unlike UT99 who was more fun even if less balanced for online play.
The thing that makes UT2004 that great it's the modding capabilities, the fact that the engine is modern enough and not so much as it's simpler to implement 3d meshes without a bazillion of texture maps.
Even if there is less mods who are my favorites in this sequel, I mean the only mods I truly play are 2341 and ballistic weapons, and from time to time some chaos UT or some random mutators or mods just for fun.
The game shines more for what the engine is capable over UE1 than its actual gameplay, it became quite simpler on some areas, and the loss of weapons like the ripper are a bit things I miss.
The gameplay is still fast and quite fun, but the feeling of the game is far away from its predecessor, that's a bit what I miss in addition to some content.
UT2004 is richer than UT99, more skins, more game modes and that's a bit why it was well played.
The thing is that UT99 had some better mods, Tactical Ops (which wasn't good on 2004) Infiltration (who is the best realism mod), Thievery (who is the best Infiltration mod in UT very similar to Thief with multiplayer), Unreal4ever and chaos UT who were better even if chaos UT have more content in 2004
Both games have a ton of skins and voice packs for your enjoyement
