Nintendo's Smash Bros.franchise has quite the roster of characters to choose from; however, due to time constraints the latest entry in the series might not see the return of all of them. There's simply not enough time, according to designer Masahiro Sakurai.
"Adding new characters is not a simple addition -- it's really multiplication. The amount of work, adding a character is multiplied and becomes bigger and bigger as you go. We can't because of the amount of work it takes."
"We're going to put in as many characters as we can, we really want to do that, because it's good for the fans and good for all of us. But in the event that we do have to cut some characters, I'd like to apologize in advance to those fans"
