Yea, the thing that a lot of places lack these days is uniqueness. And that's a pretty unique idea.. Stick with it. And later down the road, open up a brand new community to run as a sister-site with this one (such as the game forum you're talking about). Putting ads up to the gaming forum on the other will get people over there if they want to go, and not if they don't. This way, you can run two communities and make double the profit if they were both to get big.
