None of those games required additional Wii-motes. Even if you wanted to play Wii Sports with 2 players at launch it was 290 (310 if you care about multiplayer boxing).
Switch Lite with Ring fit and 2 joycons is 360. So, significantly more expensive without the added value of multiplayer.
They did if you wanted to play multiplayer which was a key element of their appeal.
$360 in 2019 ain't far off $310 in 2006, nowadays people casually buy $800 phones/tablets despite already having one that works fine.
But we'll probably just have to agree to disagree here.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
