Pyra & Mythra's Super Smash Bros. Ultimate trailer features the only script since Smash 4 that wasn't written by Masahiro Sakurai Posted by Justin 'AdaptiveTrigger' Gordon • March 16, 2021 at 3:04 p.m. PDT • Comments: 2 Masahiro Sakurai is known for involving himself in just about every part of a game's development that he's been the lead director of. It was actually quite noteworthy when it was reported that Masahiro Sakurai did not get involved with balance decisions of Super Smash Bros. Ultimate for the first time in the series. He ended up leaving the adjustment of parameters to a team so that he could focus on other aspects of the game's development.
