Tyler recently realized he is making way too many moves for each character.  He was really worried about making sure players had enough tools to be creative and got too caught up in their creativity.  Recently trying to consolidate all the move sets into something more elegant.  Putting that on top of having switchable characters and characters were starting to loose originality and individuality, so by having a tighter move set then the characters are more original and you can appreciate the diversity more.  It also means a lot less assets which mean the game can come out quicker.  A lot of it had to do with an old design idea and he hadn’t planned on having that many playable characters, he had a pipe dream of having basically the same move done in different directions having unique animations.  He doesn’t really need to do that though, he can get a lot of variety out of one animation if you design it right and use other simple rendering stuff.
