As long as you got the big exclusive hitters the came on the 3DS and Wii U to the Switch, then it should be able to do 50mil+
- Mario Kart
- Super Smash
- Animal Crossing
- More Zelda
- and others that I might forgot
This thread is about 3rd party games/support, your list is all 1st party aside from MH lol
Besides, anybody that picks up a NS knows that those 1st party games and MH are likely to come to NS anyways and is expected. People want more 3rd party support for NS or else it'll just be like Wii U and that's what nobody wants.
