The best reveals to me are the ones that balance highly accepted and/or obvious characters with controversial and/or obscure ones. That way people don't become too enthusiastic or down on the reveals.
My question would be, why do people generally not want to see fighting game characters in PSA? A lot of people seem to have a strong bias against fighting game characters because they come from... a fighting game and if they wanted to play as them they would just play that game. Seriously? You could say the same thing about every character in the game except for the really obscure ones that don't have a game out in the market that is easily available. Plus, there is the fact that PSA is a much different fighting game than the likes of Tekken, Street Fighter and Soul Calibur so it's not the same experience at all.
