For me if a game is a steady 30 fps, especially in shooters, then I'm happy, although I'm not a fan of shooters. But after playing Gran Turismo 3 and 4 on 60 fps, I'd like to see more games employ higher frame rates.
Animation and movement just seems more fluid.
I think it's cool he recognizes MGS 4, or at least the trailer. At least the developers respect each other. I didn't see a lot of effects in the trailer. Was he refering to the dust/debris effects and the HDR?
