[@Terry Bogard] Roleplaying forums are weird melting pots where people with all sorts of interests come together. When I think of niche fighting games, I think of stuff like Sango Fighters, Body Blows, ClayFighter, or Melty Blood if you want something that shows my age less. Really any poverty fighter. 

The only fighting game forums I was on were SRK, Holy Zen, and a Melty Blood forum I can't remember the name of. SRK was fine for the most part but there was always drama going on. I can see egos flaring, but there were even people selling arcade parts taking pot shots and smearing mud on each other. You could also "dislike" posts, which seems a little antagonistic. The Melty Blood forum was just a little tiny circle of friends that I joined up with, but they wanted to remove that atmosphere and be more like Melty Bread where it was all serious and they only talked about the games. Well, Melty Bread was already offering that, and they had a lot more engagement than some little nothing forum. So once they stomped out everything that didn't have to do with the game, they had no community and the forum died. I did get to know a few people but have since lost their contact info. Holy Zen was the worst. To be fair, I was quite new to forums at the time and a few members knew exactly how to have fun with someone like that. but it wasn't just me, the Admin (the guy who wrote the guilty gear parody comic) decided to shut the forum down because it was such a disaster. But yes, most of my experiences have been negative. I mostly chalk that up to the competitive nature of fighting game players. I'm glad there are communities out there where that's not the case.

I am rather enthusiastic about fighting games, even if I don't play them too much anymore. My avatar/sig combo features the priest from DFO in fact. But I'm more of an original setting roleplayer that lets themselves get dragged by their friends into other RPs. Most of which have to do with magical girls, though I was in a fighting game themed RP for a bit. I tend to not play as canon characters often because I have an unrealistically strong fear that someone will say I'm acting out of character. I'd rather make something that's my own and have it be judged for how interesting it is.

I'm not sure how you feel about hosting an RP, but I've had good luck making my own. Otherwise, 1x1 takes all sorts. It can just be a little hit or miss. But there are more of us out here, they just don't visit the welcome forum much.
