The demo for Full Spectrum Warrior is hitting the net tomorrow, so if you have Fileplanet look for it. I just hope it doesn't suck.. because the screens for the PC version don't look half as good as the consoles did. I already prepaid and preordered so I am glad to get the demo to evaluate it before it's release on the 20th.
As far as COD went I spent all of an hour playing it and was so turned off by the lag and bunny-hopping I never looked back. I may check this demo out but with all the other great releases... probably not.
