Very Good website i give you 9 out of 10, the only negative i found is your logo, you can improve it a bit more..
Looks great. I did see a couple of broken image links. For seo your H1 heading should be no longer than 10 words. Some of your images are missing alt text (description) Do a 301 direct and combine your 2 URL for the site. (naked domain name and the www)
good site. Dont fill it with useless games. better to have less games which are really good then loads of games which are average.
