It's probably still at 4.5-5.5m either way, which is really good. Would make it possibly be the highest selling non-Pokemon non-Ringfit (lol) RPG Nintendo has ever released, the only other competition is Bowser's Inside Story.

Usually the gap between played and sold is less than half (obviously also depends on the type of game and if it was available as part of game subscriptions or just had a free weekend). I'd guess around 4-5m sales.

Regardless of what the actual number sold is, it obviously sold well enough to warrant a sequel.

Yeah, whereas the first game was met with a great deal of skepticism and distaste at first, this one is releasing as the sequel to a widely liked and respected game, plus to a much larger Switch base, probably well over 100 million by the time it comes out.

Yeah, actually I remember my feelings back then. there were rumours of a Mario and Rabbids crossover before and I was kinda not too much into it. Then came the presentation and watching this my feelings about the game took a 180. They did indeed a good job convincing me that the game was worthwile.
