There's nothing wrong with new games to come out, make them rain, but the view upon Persona is as a replacement to BB right now. Everyone talks about the one and only game, Persona and the fact that it is based on that specific game is already giving it a head start. Heck, what the hell is Hokuto No Ken? The game is fun to play to mess around, but it was obviously as broken as the anime itself. It can be either good and boost the interest towards the Arc System 2D fighters or simply keep it as it is now. If people does gain interest and their games are all played at tournaments, it may also spread out and people who will start with Persona might gain interest into BB and GG later on ect ect, or stay to Persona only and never care for other games and then slowly disappear completely.
