From about 2011 onward, I saw it as the normie Mario Kart. While I played Double Dash, DS, 7, 8, etc. so many people think of Mario Kart Wii. I don't see MK8D outselling it, but MK8D is doing insanely well for a port. I wouldn't have predicted it would be the best-selling game on Switch.
Lifetime Sales Predictions
Switch: 151 million (was 73, then 96, then 113 million, then 125 million, then 144 million)
PS5: 115 million (was 105 million) Xbox Series S/X: 57 million (was 60 million, then 67 million)
PS4: 120 mil (was 100 then 130 million, then 122 million) Xbox One: 51 mil (was 50 then 55 mil)
3DS: 75.5 mil (was 73, then 77 million)
