I agree the site looks a bit plain. When you click on about us, faq etc nothing happens and the games aren't downloadable from the brief look of the site. Not enough quality content there to keep someone on your site.
Good job on the categorizing the posts and all but as everyone else yes the template is abit too plain for gamers remember most of them are crazy people (just a metaphor) too much dull colors. I'd go with a black\green\dark blue template try making it sexier for the eyes to keep em reading on your site. good luck.
