Here's a question I don't see being discussed a lot: How much of the game, in terms of modes, do you think we don't know about yet?
The main menu has 5 options, Smash (where we probably know everything by now with normal, special, squad and tourney modes), Games & More (we just know Classic), Vault (we just know music) and Online and the mysterious mode, where we know nothing about either. I get the feeling that people think we know a majority of the game's features, but there's probably a lot we don't know.
