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.
I like the piss filter in need for speed most wanted, but I think thats the only game I liked with it.
As much as people meme call of duty, they actually never used that filter in the original modern warfare games. COD4 was pale, MW2 added saturation, and MW3 was a combination of the two. But the worst colour filter has to be battlefield 3 and the blue filter.
Omg yes the blue filters are the worst, since they became synonymous with grizzled badass troy backer hero and bro-shooter archetype of the early 2000-10s
