Such a shame, cause i actually really like UT3.
Sure, it suffers from bugs, glitches, laaaag on net, not enough options to get it juuuust the way you like it, lack of maps for my favourite mode VCTF, not enough audio taunts (i know most of the voice commands for 2004), glitches glitches glitches, lack of people wanting to play, similar to Gears of War 2 (which i have never played and never seen) and is annoying sometimes i absolutely LOVE the hoverboard (board tricks and surfin like a pro, anyone), the art direction is stunning, the AI isn't on rails and it makes me feel a little closer to playing against human players. Also, i do like the improved graphics...
And let's not forget my favourite mutator... that Slow Kill Time thing, it gives me the time to, after i've just jumped from a ledge into the middle of a red team massacre, see teh blue flesh fly and look around to see the seven other guns pointed my way.
Makes me actually consider joining up online. Not that i'd ever be able to spend enough time online to enjoy being pwned.
