What would you like to see in the next Smash Bros?

[Cheebee]

I wouldn't really call the inclusion of Sonic and Snake in Brawl a surprise, not by any stretch of the imagination... everyone was already practically expecting them to be in there by the time the announcements were made.

As for additions to a new Smash Bros., well, I wouldn't count on too many characters from companies other than Nintendo and 2nd parties. Definitely not the likes of Master Chief. :p And I honestly can't see them adding an endless supply of new characters anyway.
I really can't think of too many improvements I'd personally like to see, apart from improved graphics and improved online. Maybe Tingle as a playable character. ;)
