Nah, most people prefer multiplayer games. You used Nintendo as example, but the most popular Switch game is Mario Kart 8, followed by Animal Crossing and then Smash Bros. The "quality singleplayer game" (Zelda) comes in 4th place.
PlayStation?
Look at this. The "quality singleplayer game" (Spider Man 2) comes in 6th place after a bunch of GaaS.
Roblox is more popular than Spider Man.
The most popular game on Steam (and Xbox) right now is Palworld.
The PS5 sells more than the Xbox because Microsoft's big multiplayer IPs aren't hot anymore.
Singleplayer-only gamers need to be humble and admit their favourite games will never be as loved as multiplayer kings
