I was reading through the SRK thread and one thing that caught my eye was your (trag) faith in Brawl's ability to bring players who crossover into the other fighting games. I can definitely see how that is exciting from Evo's point of view, bringing in new blood for games that have been out for very, very long.
My question is, is the actual number of crossover Smash players even close to the potential? A question to Smash players out there; how many of you seriously play fighting games that are not Smash (by seriously I mean attendance at the big tourneys, ranbats or regional tournaments, not online or casual play). Especially the games that will probably end up being in Evo (MvC2, 3s, CvS2 looks very popular as a keep) or are in consideration (Arcana Heart, Guilty Gear, Melty Blood, Soul Calibur, Tekken, Virtua Fighter)
Edit: Forgot to write this in.
My thought on SSBB creating a huge amount of crossover player potential is that it probably wouldn't bring more than a few players. SSBM was a community that was brought up basically independant of any existing fighting game community. Since we've built up our own community, with our own extremely hyped tournaments (Melee-FC, OC) with attendance numbers that beat Evo's Smash tournament, and since SSBM is so fundamentally different from 2-D fighting games in general, there isn't much incentive to try out any of the other fighting games. That and the dislike SRK folks have towards Smash (I wouldn't know if the feeling is mutual) seems to discourage any Smash players from getting into the other games.
I'm not speaking for myself (I am in hiatus from SSBM itself, I'm slowly learning 3rd Strike and I really like CvS2) but I'm just speaking from what I observe from the community.
