notice a theme here? people with old video cards are the ones saying they aren't excited about Crysis. i think they want to play it to, but know they won't be able to.
People who don't upgrade very often like to play older games because they're tried and true and provide the kind of gameplay they like without necessarily looking good. They'll play Crysis when they hear about how it does and have a chance to upgrade.
Personally, I'm not at all excited about Crysis. There are other games I'd rather play.
