1 for not posting a direct link and making me copy the title

Your images are saved way to low of quality. I'm a web designer/graphic designer so i notice things like that, most users probably won't. You bought the template, one that alot of other sites are using. Infact I'm helping someone install it on another site. Only thing different is you didn't fully change the colors and really only used the category background. Same graphics from same template...
Your left menu: Your section headers are cut off and not showing the full stars. you should consider maybe taking the cellpadding to 0 to help fix this.
Alot of the site is just left from the standard template as far as colors go. Go in there and get creative.
Game pages: the game description is far to cramped allowing only 2-3 words a line. make the options table smaller in width. Doesn't have to be 50/50 but something else...long descriptions will look horrible.
There isn't a home link other then clicking your big star. Put a "home" link before "Action". Not everyone knows if you dont see a home link to try to click the logo.
Try droping your banner on the main page too. just put in a break tag, and allso be a good idea on the banner image to put a property of 0 for border to get rid of that blue outline.
Overall: 4/10. Get creative, have some fun. There are hundreds of PHPAS sites out there that are using either the out of box template or one with only a few graphical mods there for they don't stand out. I made the company I worked fors site stand out and really put alot of time into it. 9am-5pm 5 days a week for 4 weeks. And there is still stuff that needs to be done yet. Granted a week of that was because i upgraded from 2.0 to 3.0 and had to completely redo the entire site after i just finished it 2 days before it came out, haha.
