While UT3 is definately not without it's faults, I have been enjoying this game a lot as of late (purchased it from STEAM a few weeks ago).
The bad: the UI (and especially the server browser) is horrible, the "consolisation effect" is definately noticable. But seriously, EPIC can make a game that pushes hundreds of thousands of polygons per scene at a stable framerate of 70+ fps, but the stupid game menu is jerky and slow? WTF?
The broken server browser might be one of the reasons for a relatively low amount of people playing this game, it's serious broken. First of all, it's only showing maybe 30% of existing servers at any given time and to top that off, it's misrepresenting ping times, when the server browser shows that I have 80 ping to a game sever, in reality when I connect I usually ping 50-55. For finding games you definately want to use SKUT3 (an mIRC addon) instead, you can download it at

The good: actual deathmatch gameplay. One of the problems with UT2004 was the fact that it was very easy to get away from your opponent forcing a lot of fights to become long-range histscanfests. UT3 has had its movement toned down a little bit, which ironically made it into a faster game with fierce combat, the combat is a lot more about closerange all-out fights to the death.
The game is absolutely stunning for the most part (although there are obviously a few very average-looking maps), very highly configurable through the game interface and editing the
.ini files and runs very well on moderate hardware. I have a C2D E6600, 2GB ram, 8600GT 512mb and WinXP SP2, which is pretty much midrange these days and I am able to play the game at 1024x768 with all world/texture details on highest settings and a stable 70+ fps framerate as long as I tone down some of the unnecessary effects like dynamic decals and explosion details.
