I consider the game being in arcades and Japan for like 2 years before worldwide release to be its “launch”, so that’s what I’m referring to.
My comment wasn’t related to Aeon at all actually. My point is more that most people aren’t dumping significant amounts of time into each and every character in a roster (any roster), so delaying a title for months and years to add oodles of characters just isn’t worth it. So long as a roster has 20ish characters that play differently it’s likely that you’ll find someone that interests you. And if you don’t, then don’t buy it! And I don’t mean that in a sarcastic or combative way either; if a game doesn’t have any characters that interest you, then don’t waste money on it. If it’s unplayable until Amazing Character X is added, then by all means wait until ACX is added before picking it up. Lots of other people (hopefully anyway) will enjoy it in the meantime, and you can join in when your beloved character or playstyle makes it in too.
And on the competitive side, @BigBadAndy is right. Soul Calibur is already an insanely MU heavy game, to the point where even spending hours each week playing the game constantly yields new strings, positionings, and character-specific tools that you have to learn or lose to. It’s almost overwhelming already, and I’m FG literate and have people to teach me. Launching with 30+ chars would just feel utterly unmanageable.
