Nintendo has Mario, Zelda, Kirby, Donkey Kong, Starfox, Pokémon, and a few other less super famous and internationally known IP franchises. The core games and their spinoffs make more games than most children can reasonably expected to play through childhood and early adolescence. That the machine then collects dust doesn’t hurt Nintendo because they already sold it.

Yes Steam has huge library (my ‘want to play’ list is over 100 titles at this point) full of games of all genres, qualities, and niches. But Nintendo has more than enough to do what they have done for years, i.e. sit tight on their beloved IP and dole it out at varying levels of quality on strictly low end hardware and watch their earning go up.

Steam Deck has a tiny install base.

Switch 2 does not.

I'm mostly a PC gamer but let's be real here.

Very true, but that tiny library happens to occupy like 80% of the biggest IP.
