Me too, I was thinking about how I was looking for an upgrade to the Linux UT 2003 a while back and couldn't find it on the official site. I decided downloading it from some random place was risky, and here was almost my reinforcing, validating catharsis - but alas, it's just about some IRC client that nobody uses.
Yup, very bad for a lot of smaller IRC networks; 3.2.8.1 is the latest version of UnrealIRCd and what most of them (assuming that they are up to date) are on.
It was a very good game. A couple months back I found the original (Windows) CD and wanted to install it on my Linux netbook, but, unfortunately, couldn't find it. Gave up completely.
