Anyone got any idea which shops (if any) still sell this game, and whether or not I'll need some special kind of program to run it on Windows XP? Cheers

Try online stores, like Amazon. Also, The game stores in my country (Finland) still sell it. Also, try CD-ON (http://www.cdon.com).

The game runs like a dream on my XP, and I only have the patch installed. However, other people have complained about crashing, freezing and other problems. Perhaps I just got lucky.

EDIT: Never mind CD-ON. Looks like their EU version only sells music.

Cheers, I'll try looking about on the net!
