I really hope it's gonna be good and I hope Illumination doesn't screw that up.
Last year was actually interesting as we did see the first crossover of Mario to another company pay off with flying aces, at Ubisoft with Kingdom Battle on the Switch.
I would suspect they would have Miyamoto and Melendandri on close tabs with this project, to ensure that it doesn't have a bad sign of quality.
And in a sense, I guess we have to give thanks to UC for this one, as they seemed to convince Nintendo well enough on Super Nintendo World to the point of where 3 versions were planned in that instance.
