What is the interface like? Does it still suck?
Yup, still sucks, as it is the same UI it allways was.
It is slightly less annoying though, as they have tweaked a few things, it has a new black skin which is nicer to look at, some redundant "press any key to continue" screens where done away with, you can actually see the map in the background of the main menu now (why they would put a 60mb map in the main menu, which you have to load constantly, is beyond me! but atleast you can see it now, so the 60mb aren't entirely wasted like before), there's actually usefull setting in the advanced vid-settings menu now instead of 3 sliders, the server browser has had some tweaks make it more reliable, and the Instant-Action menu now remembers its settings.
Thats pretty much it, the UI seems more polished now, and some annoyances have been delt with, but it is still the same fundamentally flawed UI it allways was, it still flows and opperates the exact same way, it still takes too many clicks to get anywhere, it still has too few options per screen and huge text (good on them tharr consoly machines i hear! yup), and it is still sorely lacking a whole bunch of options that we knew and loved from UT and UT2004 (especially when it comes to instant-action, which has not been touched on at all, except for the menu's now saving you selected options).
