Congrats noccer! Welcome to the old-fashioned club! Don't let it get away from you though...it is an illness that knows no limits.
TU comes in a number of flavors: big/thick, big/thinner (NA/EU) and a DVD case.
Big and thick:
big /thinner (NA release):
And a DVD case edition which I don't have because it's pretty common and I can get it anytime, cheap.
The Unreal Anthology is a good one to pick up as well, containing all that TU has, plus Unreal 2 and UT2K4.
German edition with no UT (as per noccer's explanation)!
