With just over a month to go until Princess Peach herself is getting a new adventure called Princess Peach: Showtime, it looks like we have learned an interesting detail regarding the game. A Chinese box for the game, noticed by Akfamilyhome on X, reveals that it has been developed with Unreal Engine instead of using Nintendo's in-house tools.
While it wouldn't be the first time this happens, there are currently only two launched first-party games for Switch using Unreal Engine; Yoshi's Crafted World and Pikmin 4. The latter was released last year, and it could indicate that Nintendo has decided that Unreal Engine is a more convenient and effective tool for at least some types of games - or that Princess Peach: Showtime is developed externally rather than by Nintendo themselves.
Princess Peach: Showtime premieres exclusively for Switch on March 22, and we will of course share our review in time for the launch.
