It's either Mario Kart or Pokémon, not Super Mario or The Legend of Zelda.
But it's tough to say because Switch had 2 Mario Kart titles (an enhanced port and a more niche and expensive AR game) while it had tons of Pokémon titles and a lot of them were RPGs. I don't believe we have data to say which motivated more sales, but I have to think it was probably Pokémon in the case of Switch.
For Switch 2, it might be Mario Kart. Its attach rate is insane and it's a new main Mario Kart game which has not happened in 11 years. I'm interested to see how much Pokémon Gen 10 will boost Switch 2's sales, because they're already record-breaking as is.
