just finished the single player of COD4, its fun but a bit short. Online and lan is hours of fun though. Crysis is fun, played it on a friends system and seems like it would be worth a go through. BTW they play fine on my laptop, Everex XT5000T, which my friend also has. Only upgrade is a second gig of ram for a total of 2 gigs. Which vista is more then happy to help eat up.
