Origami King being Switch's first Paper Mario game, releasing in the supercharged pandemic year, in the middle of the Switch's prime, and most importantly being an original title, makes me think that it's unlikely to be unseated for best selling Paper Mario game on the Switch. I think Super Mario RPG had much more things going for it than TTYD does, being a much more significant legacy title, having a more traditional Mario presentation, and getting the holiday boost, but even that closed out the quarter at a solid 3M and will probably merely squeak itself passed Origami King in the long run considering the frontloaded natute of RPG sales. People place faith in word-of-mouth a lot, but on the other side of the aisle we see it do little to help a game like FF7 Rebirth, so I'm not convinced TTYD will have miracles manifest itself either; even if it'll likely sell well enough and leave Nintendo happy to get good ROI on a painless remaster.
