Nintendo has spent decades building an extremely loyal, multigenerational consumer base. They also release very popular, high quality games. I have no interest in owning a Switch, but I get why so many people do.
The vast majority of Steam games can be easily cracked and played offline if they ever go rogue. Modern console games are much more difficult to jailbreak like that.
Ah yes, the one Nintendo IP that has gone to shit. Not fully by the way, as Legends Arceus was fantastic, and even my mom who hasn't given a fuck about Pokemon since Yellow loved watching me play it. If Gamefreak would finally make another side game like Mystery Dungeon (or the more forgotten cult classics like Pokepark, Ranger, Conquest, Rumble, etc.) we wouldn't be trolling them so hard. It's also more of a Gamefreak problem than anything, as other companies that did Pokemon games (Chunsoft, Genius Sonority, etc.) did fantastic.
Anyway Zelda and Mario are still making bangers, Kirby Air Riders is coming back, Metroid fans are fed, Splatoon is getting a whole new game for Switch 2 (fuck me...), people are still relatively happy with Animal Crossing NH, we'll see how Donkey Kong's new game does, and while FE's newest entry wasn't so hot you can't ignore how Three Houses brought in a brand new wave of loyal FE fans.
Literally everyone knows Pokemon mainline has been going to shit (and not the characters, designs, music, etc. imo, just the animations and story writing). Pick another game, even Nintendo (and Pokemon) fans make fun of it.
