I've got wolfenstein on the PC and I love it but I want to try it out on my new iMac first to see what the performance is like before I buy it. Is there a single player demo out for RTCW?
I heard there was one at MWSF, you might find it with some download-app, but there's nothing official on the net.
Only Multiplayer, and that's the good part of that game anyways...
