Speaking to Nintendo Dream magazine, Super Smash Bros. producer Masahiro Sakurai talked about the game's character roster.
Sakurai started off by describing now newcomer Greninja was included in the games, simply based on several illustrations that he'd had received, prior to his name being decided.
By May 2012, all characters were decided and as production ramped up, the team "cut out low priority characters," which, unfortunately, Sakurai won't disclose. One of the newcomers, Bowser Jr., was almost cut, however. Sakurai admitted that the team had "discussions on giving up on something many many times", but the staff persisted and he made the roster.
There were event aspects to characters that Sakurai hadn't thought about, though, for example "Sheik's movement is completely different to Brawl, someone made a proposal to me for those motions," he said.
What characters do you think were cut from the game?
