UT was the first game I got for PC, I ran over and got it the day the PC was delivered to my house.
The music and ambience was just far beyond anything I'd ever seen before, which was why I bought it with such haste. I was really saddened by the UT2003 music which was a step or five below the awesome UT sound and thus I could never be bothered to get UT2k4 which I've never heard anything about soundwise. (even the demo had forgettable music if I recall correctly.
Legend. 10/10 because there are SO MANY good songs that make me want to jump around and shoot shoot people.
