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.
It's funny to clown on nerds using "the meta" using non meta stuff yourself. Beating them flying their f22s in ace combat using an F-2A or MiG 21. Beating the meta cars in Gran Turismo using a GR3 Volkswagen beetle race car. Them rage quitting in the game chat and direct messages is comedy fuel
lmao I fly the Mig 21 in DCS, get a player kill in that thing and people are just so impressed they can't even get mad. Just gotta use Vietnamese ambush tactics and know when to commit and when to run.
