Haven't played much BF:Vietnam yet...so it'll have to be for UT2004:
Map: Plunge, high up on the skyscrapers and low gravity...way cool. (If only I could stop falling to my death!) :lol:
Weapon: Minigun, it's an old classic and I love it. :D
Vechicle: Not a big fan of the vechicles on UT... :(
Skin: Those cool looking robot guys. :D
