Looking at the current line-up:http://www.playstationallstarsbattleroyale.com/All-StarsI saw enough familiar faces to be content (Drake, Jak, Ratchet, Heihachi, Coles, Parappa, and Kratos) with the launch characters. Truth be told, I was on the Crash bandwagon (the whole "include Crash or you've lost a potential buyer" mindset), but then I played the beta and absolutely loved it. I then realized how crazy it was for me to base my entire purchase over one character. I'm still bummed that Crash may not be in the game, but there are enough characters, both old and new to keep me interested in the final product.
I've been looking around the board and most of what I have seen are disappointed people listed the characters that they wanted in the game. I don't really have the right to say anything when I barely know who half of their wishful characters are though. But anyway, as the title says, who is happy enough with the current 20 characters?
