Won Free Lifetime Hosting, Need Domain

Keeping it short and sweet, I won a contest on HF for a free lifetime premium subscription for hosting on a guy's site, so I figured I'd use this opportunity to work on my web development/graphic design skills and put up a site to give me something to work on. Anyone have any suggestions for a domain to use? The domain can be about anything, just as long as it's a set niche, like a Zelda forum, a Runescape forum, a general forum, etc.

IMO if you are just messing around the domain can really be anything. Just make it something that you will have fun developing and get started.

I think this may go completely against what you just said, but I think a more general forum would be more interesting and easier to keep up with. Something similar to FK imo. GL man.
