Disclaimer- I'm not a web developer, but I am an artist, so this review is based on that & my natural geekiness, rather than the source code. I hope it's helpful, anyway.
Your site is very clean-looking. I like that design style. Everything was orderly, intuitive, easy to find what you're looking for.
As gaming is definitely not my field, I'm not sure what you are aiming for, but the header is very plain and understated. Without cluttering it up with non-relevant images, etcetera, I think it could definitely use a little more "pop" to it.
I think simply reversing the color scheme- make the text light and the header background pink- would make a big difference! (I did a quick PS to explain- not good colors, but that idea)
