Super Smash Bros. creator Masahiro Sakurai has confirmed that in the last three years, he completed a proposal for a brand new, mystery game.
This was revealed during the final episode of Masahiro Sakurai on Creating Games on the developer's YouTube channel. After revealing that all of the channel's previous videos had actually been recorded in advance – two and a half years ago, to be exact – he says that in July 2021, when he was working on Super Smash Bros. Ultimate's DLC, he "received a request to write a game proposal, which I finished at lightning speed."
