The color scheme doesnt somehow look appropriate for a gaming site, it also looks like it is under construction due to links not working.
Also the site needs screen captures of the games you are selling to spice it up.
The choice of colors is entirely up to you, those colors look too bright, something easier on the eye would look better.
An example of a games site i like is abcarcade.com
On the games page it says
""Pick a genre to see some great games! Note: site under construction - little or no games at the present moment" Action :: Arcade :: Car :: Platform :: Puzzle
my suggestion. Get rid of the bright blue background. go with something softer. I would like to see a dark grey or something like that. Whenever i visit a page that has such a bright background, i don't even give it a chance, i just look elsewhere
