Hi - good start I think and game looks appealing but that patterned background took a long time to download for me and draws the eye away from the 'action' in the middle of the page as it's so busy. I'd really recommend cutting the copy right down, there'a far too much info on the page. At the very least, think of the 2 or 3 main things people need to know on each page and put them topmost, with maybe a link to more info if they need it.
That homepage image of players does not look fun at all! it's more of a wet Wednesday night in a youth hostel - I really want to see some of the game play or some artwork from cards themselves. Or maybe a cartoon evil squirrel punching a rat...this image is far too sedate and static.
Finally, make your CTA (call to action) far more prominent. What do you want a site visitor to do from your homepage? buy the game, subscribe, comment? pick the most vital and make it a big feature. For instance, Amazon REALLY REALLY want every visitor to buy or find out more about kindles - check out their homepage which shamelessly promotes them. Your first post of call might be to create an information hierarchy by using title headers (h1, h2, h3 etc) which will help you prioritise parts of your copy.
Hope that helps!
