i liked the DEMO more than anything i think, the awesome music and SE7EN reminiscent intro was simply awesome. the GEISS effects were damn nice as well 😉 but when it showed the Earth shot and zoomed in to the nature scenes with the trees i was blown away, even the matrix scene didn't impress me as much as that did.
but the best part i think was the quickie game- for those who can't play it you get to play the demo of the truck w/ missile launchers on the back blowing up alien spaceships (the scene from terminator, yup 🙂 ) that was shown in one of the demos. it's actually quite playable, DAMN if that was a real game i'd seriously have a fat hole in my pocket 🙂
added note: for the soundtrack to the DEMO look under your \3DMark2001\music\ dir, it's just an mp3 you can burn straight to CD.
