I agree with you there. I would rather hear about the gameplay or how well certain concepts worked, instead of having to skip through crap about how average the graphics and sound were. I am sure that in some games those things might stand out, but, if they don't, ditch 'em.
Also, another thing that has annoyed me is when I read a review titled "THIS IS THE WORST GAME I'VE EVER PLAYED!!!!!" then I see a 7 out of 10 rating next to it. If the game is so awful, then why the heck do you rate it 7 out of 10?
