After all the hard work Epic put into making UT2004 run on Linux and Mac?! What a slap in the face to the poor Epic developers!
It's a LOT of extra work getting a game to run on multiple platforms, and I'm sure the payoff doesn't even come close to the extra development cost. It's disgusting that someone would try to undermine Epic's great platform independent work by releasing "XP only" maps. UT is NOT an XP-only game.
