I've... found it very difficult to focus on work today, what with my Diablo III collector's edition having arrived this morning.. But I managed! Sort of. I'm experimenting with the possibility of placing account settings and character settings in boxes above the main navigation - this would double up as boxes for the login and registration forms. Registration should be able to fit in there as well, as I'm planning on making it as quick and simple as possible - not really any longer than the login form. I figure that if people can register quickly, then we'd lose fewer users at that stage.
Behind all of this, there would be a background illustration intended to capture and hold the visitor's attention. Not usually a strategy I've used before, but it seems to be a functioning trend across most game websites. Here's a rough exploration of these strategies, minus the illustration.
