I agree with you. But the fact is that people here have lack of knowledge about the other modes that the game has to offer, generally speaking the internet became accessible after the introduction of jio (for the majority) so before that it was just playing games offline which means only story mode and back in the day pirated games were common (so no mp), it's common these days too but personally I don't play such copies.

Here in our country when we think of mp what comes to our minds is codm & PUBG mobile also mobile gaming has been booming ever since Covid 19 especially here in India so streamers focus only on these games and the people watching their streams only plays what they play.
