When your primary method of establishing identity is that you play lots of games, there is a very serious lack of identity there.
I play plenty of games, but I also read and write, go outside and run around and am generally a fairly well-rounded person.
To establish your entire self on a singular hobby and become so vociferously protective of it to exclude others and mindlessly consume whatever you're given is generally not something to have dignity in.
I mean, there's nothing inherently wrong or embarrassing about liking games.
It's this weird concept that there is some uniform culture that exists solely for games that gets on my nerves.
It's a marketing gimmick more than anything else.
"Play this game, buy this console or you're not a real gamer.
Fuck Nintendo, there's not enough killing, 420 dank memes are the height of comedy, etc."
It's like, holy shit.
When did it all go pear-shaped like this?
