I think designing it as something that is more of a "landmark" is the best way to approach it. I really love GF but as you said, there isn't much "news" to speak of. I think dividing it into sections like: Downloads, Fan art (w/ user submissions and comments whenever), tech support (w/ things like FAQ and information like you said), fanfic, videos, screenshots, where to buy, relevant articles, etc. All of those things that you talked about and whatnot would be great.
I'd say just design it so that it's not a "constant update" kind of thing like you see at mixnmojo since there's not that much to talk about on the news front.
That's just how I see it, though.
Hope that helps a little!
