Personally, I really don't see the scene in Hawaii expanding because of the lack of an arcade cab. The BB scenes in the US aren't very large to begin with, so it's understandable that Hawaii doesn't have a large scene. We have 3-5 people who play the game. I don't mind meeting with these 3-5 people when I come back for breaks just to get some casuals in. You just gotta take what you can get. 3-5 people is a small amount, but that doesn't mean they shouldn't meet to play. What we do here in NorCal is a monthly ranbat on the first Saturday of every month. We play BB, GG, MB, and a couple other games. Of course, there are a lot more people, but it's basically just a huge "hangout" day. I'd suggest trying to get together once a month with as many of the BB players as you can and try to get some regular gathering started. Even if it's only 3 people, then so be it, but just enjoy it.
