I'd have to say I agree. As fighter also said, a better framerate wouldn't hurt.
But as for environments, as long as they keep the gritty look, I'm fine. The first game's environments were true perfection. Killzone 2 got a little bit repetitive, even though I can understand why. They could add unique details here and there, though.
They should also put in a knife.
Rockstar: Announce Bully 2 already and make gamers proud!
Kojima: Come out with Project S already!
