Other than the gray background, there isn't much wrong with it. The color just doesn't go well with the rest of the site imo. Perhaps a lighter shade, or just a white background would work. Also, the footer looks funny since the width of the body does not stretch all the way to where the footer is. The gap looks odd and confusing. It may be just me though.. I'm on a widescreen monitor.
Also, the banner logo/text seems random and not really focused on 'games'.
Hope that helps..
