I really like the layout and design. I especially like that I don't see any flash, just jquery!
The articles will need rewritten though. I don't know if these are just placeholders for real reviews but they aren't written professionally. There are some standards that I don't know about that you should look into if you are going to write them yourself. For example, you aren't supposed to talk about yourself in a review. Leave yourself out of it. Try not to use the word "I". Remember, the reader doesn't care what you think, they want to know "how will I like this game".
Use phrases like:
"If you are the type of gamer that _____, this game should be blah blah blah."
"Blah blah game has really changed the game with their latest release. Blah blah"
I'm not an editor so maybe someone else can give you more tips on that area.
