Ha! I was about to compliment OP on such a well-written post, but then realized that it was written by. LOL.
Anyway, I can't say this looks very interesting at all. Then again, I've never really been a fan of the Smash Bros. series. There are some hella weird character choices on the Playstation front though. Parappa the Rapper? I love Parappa the Rapper, but the last time he was in a video game was a decade ago. That's more than a bit of a stretch when Sony is presumably aiming towards a younger crowd. And if the game is aimed more towards kids, it might be a little problematic that Kratos is one of the main fighters in the game.
