Just got my copy today. I guess us North American folks have the 5 CD set, whereas the Euro crowd get's the 1 DVD version. I didn't get through the demo, but it blew my mind. God knows when Half-Life 2 and Doom 3 will be available, let alone see a playable demo (that we can download). I've been reading how it's taking well over 20 hours to get through---something I want. With my work schedual and training, I expect it'll take me awhile to get thorough. :chk: Excellent.
