Actually I played the GT3: A Spec demo at the SF Auto show and it didn't look too impressive. The biggest thing was lack of anti-aliasing which detracted from the overall experience. The models look great, the control was great, and the feel was even great. But my first impression was "that's all Sony first party could produce?"
But GT3 has been delayed once again (until March '00) or so I've heard *sigh*, so hopefully they're delaying it for good reason. I'd rather have a polished product then have it before next year.
Anyways, here's some photos I took at the auto show if anybody is interested. No GT3 pics though sorry!
