I started with the Multi gaming version after a request of crushedsouls. Thanks to him this theme turned out very well :D. Then I made some other headers, for GT5 and made a complete GT5 theme out of it. I hadn't seen a GTA4 theme either and since I like that game very much I made a GTA4 theme out of it aswell.
The themes come with matching forums and custom your account images. There is a gaming image background image at the bottom center and they have a vista looking rollover menu.
