I'm surprised there's no topic for this yet. Anyone else playing it? Been a fan of UT since the original in 99, didn't like 2k3 nearly as much. 2k4 was better but still not as good as the original I thought.
UT3, however, seems like it will take the top slot though. The weapons are great, the movement is great... the entire feel of it is just spot on to me. Unfortunately there's only 1 vCTF map in the demo, but it's a good one (also 2 DM maps, but DM doesn't really interest me).
There are of course issues that I hope they address (mostly with the UI, but a couple balance issues as well), but even in its beta state, it's great and well worth a try.
