The site is near perfect, it's a great colour scheme but the only thing I could see that would need adding is some information about the site or show guests some way about what it's showing. We know it's a games site but not what type of games site and what it can do. Apart from that it's great.
The navigation bar-when any category other than Games is clicked its color should be same as that of the page. Even when 'Action' or any other category is clicked it appears as if 'Games' is clicked. Also, the tag cloud needs improvement. Individual tags should get highlighted when the mouse over.
