The other thing I'll say is that a bunch of characters you haven't seen yet do a great job of really establishing a unique play-style, so when I look at the game less in terms of "is so-and-so in?" and more in terms of "are there a LOT of different, fun ways to play this game?" then I'm really pleased.
As it happens, my current favorite character to play (not yet announced) [Editor's note: This was written before Amaterasu, Thor, Trish, Chun-Li, Super-Skrull and Doctor Doom were announced] would probably be my LEAST favorite character in terms of "did I want to see this one make it into the game?" So basically the fact that I am not a huge fan of the character didn't matter to how much fun I actually have playing them.
