There are two major issues that we are overlooking it seems. BB has not been around as long as other games that appear in EVO. This is part of the reason for a smaller, less established fanbase. The more established franchises that have been around for over a decade draw in bigger crowds and more money so they get first dibs. The possibility remains that BB will become more established with time, but its unlikely as arksys will generate an entirely new franchise with the ps4 coming out soon.
Number two is the game does not appeal to a wide spread audience to begin with. It appeals to anime fans, which is its intention. With anime being relatively unpopular in the U.S. this also cuts down the audience and adds to the reasons why it will not appear in EVO.
Trying to force feed people who bash the game will only increase the bashing and polarize the FG community towards the more established games. The best option would be to demonstrate that the franchise can attract a crowd and earn a profit. That is the only thing the people who create these tournaments care about anyways.
This is just my two cents though. Its a shame, because I feel BB is much more entertaining to watch than SF or SC. Footsies......footsies everywhere all the time.
