I started playing UT when it was first released and the first one is still my favourite although I don't have it installed on my PC at the moment, but the 2004 version. Unfourtionately my computer is shit when it comes to new big games and it doesn't handle the new UT3.
I don't play UT as much as I used to coz I love this game so much and I get so into it, basically when I'm playing it then I curse and scream at the bots alone at my desk with the headphones on.. Pretty weird sight.
But still, every now and then (especially when I'm in a bad mood or angry) I take my fave map Curse II or III, make the bots beginner, name them after the persons I'm mad at and just KILL THEM ALL MANY MANY TIMES WITH MY FLACK CANNON!
But I'm at work most of the day and the other part of the day I sleep, therefore I'm not online enugh on my own PC to have a netgame going on, although it would be fun.
