It does take a pretty mean machine to run it. I had been running it with everything but basic lighting turned off/at the lowest setting until now. Upgraded to a 3GHz Core 2 Duo, 4GB RAM and a 1GB 9800GT and I can do full detail. Unfortunately, I upgraded to Win 7 at the same time and ran into the problems in my previous post. The port quality is not too good. If you can get it for the 360 I imagine it'd be a no-brainer. With PC it's a mixed bag - if you are ok with using lower (or lowest) detail settings it's an endless bag of fun. Even today I still hear a new bit of dialogue on the radio or something now and then that makes me laugh, and I do something wacky and funny practically every time I play, often by accident and even now where my play sessions are spent trying to find a way around that bug.
