I mean, that link was probably too focused on romance stuff, but I'm talking about the sort of dudes that fit that profile, their attitude, aesthetic, and humor. I would venture to say there's a lot of overlap with like Hot Topic emo-punks. Theater techs is another proxy. Sensitive redditors. Like, people who quote Monty Python sketches at length, say things like "you amuse me", post anime reaction .gifs. I'm kind of punching down here, but it's not really straight nerd-dom either, as it involves a particular mix of pompousness, unintentional cringe humor, and twee sensibility. Fedoras are kind of an ineffable symbol of this (cringe), and I found that Undertale exuded that ethos with every fiber of its being, on top of being a plodding, shitty game.
If it was a hipster thing that would be a major step up (though still bad), because at least the pretentiousness wouldn't be so stunted and insular. I might be too old at 31, but having spent a decade-plus in the hipster hotbeds of a small liberal arts college in the NE and Brooklyn, I can say that I've never encountered a video game hipster. Video games were considered one of the lamest forms of activities by these people, outside of nostalgia Goldeneye or whatever. No contemporary discourse.
The most hipster game I can think of is probably Journey, but you've got to own a console to play it, which excludes the majority of that demo in my age group/social sphere. The (few) people I know in meat space who keep up with games at all do so in a sort of sullen secrecy, treating it almost like porn (as do I; posting here is my only outlet).
And really a hipster gaming posture would be like, this one ColecoVision game forecasted the contradictions of the medium in 1983. Or even like Deadly Premonition is vital programming, which attitude does exist to an extent, but not really as part of a developed aesthetic/academic posture toward video games as far as I've seen. My hipster opinion would be that Stephen's Sausage Roll is one of the most important games ever made. And that Toki Tori 2 is the best game of its generation.
