Hardcore gamer = someone who plays only cinematic grizzed white dude games and/or military fetishizing FPS
Casual gamer = anyone that is not a 15-25 yo male, and/or plays anything outside of the previously mentioned games, especially if those games are colorful.
So basically the gaming community is full of gatekeeping, misogyny, toxic masculinity and general chuddery. They make sure they’re the loudest voice heard when anything about games is talked about, and won’t be happy until all games a homogenous stream of bland, hyper-realistic but with a grey filter slog of mindless action with no heart or soul. And don’t you dare force them to read any dialogue or story.
Epic G!mers got so locked into what Real Pro Esports Take This Seriously Please MOBAs were supposed to be that they bragged about how a foregone conclusion match could drag on for over a half hour and just invite more enraged slur flinging all the while. The “meta” of the entire thing is so bleak and joyless that when I directly asked a few enthusiasts, in person, what they actually enjoy about it, the most common answers were, I kid you not, “the winners make money” and “the drama; people get so mad.”
