Sure, there are people who break the mold but even then they are insular minded. When it comes to video games, they are only interested in Call of Duty or Halo; Blizzard titles but especially Overwatch these days; Mortal Kombat and occasionally Street Fighter or Tekken; Bethesda games but largely just Fallout, and Nintendo games. They either have never heard of or trash franchises like Disgaea or Guilty Gear. Even Final Fantasy gets considered “gay” by them on occasion.
This is why I dont really interact with other gamers, or try too much to talk about games with people. Most of my friends, what few there are, are like this. Dont get me wrong... while some of those games are crap, some are good. I've certainly always been a fan of Nintendo (but they do stupid things at times). But.... ehhh.
I'm a big fan of indie games mostly... quickly was disillusioned by AAA games a few years ago when they started going downhill. I've also REALLY been into Guilty Gear (the older ones mostly) to the point that, as a cosplayer, my main cosplay has always been from that series. Bridget, specifically. Back in the PS2 days everyone knew who that is and the series as a whole. But in more recent times, well... my nickname given to me by certain friends is "Rosette" because everyone mistakes me for that character (outfit is similar) when I'm doing that outfit. Which would be less embarrassing if I hadnt heard the name so much that I'll automatically answer to it. I'll never hear the end of that.
*ahem* Back to games... Retro games too, for me, huge fan of those. Heck, the whole reason I got a VR setup was so I could create a virtual 80s arcade (uses roms, and I have *all* of them). Pretty much all of my favorite modern games are indie stuffs though. Some are ones that a decent number of people have heard of, like Binding of Isaac or FNAF. Others, not so much... games like Streets of Rogue (one of my favorites of all time, period) and Hyperrogue (good luck finding anyone who even knows what that is. Heck, when it comes to not knowing games, well... you are the first person I've seen in a LONG time who even knows what Guilty Gear is. Which is depressing, considering how HUGE that series used to be.
And I tell ya, it's always been frustrating. Talk with the average gamer, and they not only dont know what any of those are, they wont even consider trying them. They dont have TEH GRAFIX. Those same players will then fall for lootboxes and other predatory crap, the blasted fools.
The one and only place that is an exception to this is Steam. I've met quite a few people on there who are into indie games and things like roguelikes or shmups, two genres that dont even exist on consoles because they wouldnt profit the Big Guys as much as yet another COD. I'm glad Steam exists for this, but of course that's a long-distance sort of thing. It's rare that I get to meet any of these friends in person (but it has happened a few times).
Anywhere else though? Just an exercise in frustration and idiocy. Not to mention absolute jerks. As much as I loved Guilty Gear back in the day, it was annoying to actually play against people in that community, since SO MANY of them are just nasty. And that's frustrating too.
Outside of gaming, everything else you say is quite true as well. Most of my family is like that. It's all football (bleh) and politics (BLEH) with them. They often wonder why I'm such a recluse. I tend to think it's rather obvious, but nobody seems to grasp it even if I explain it to them.
And ya know what, it's the same with anime as you said. Dont get me wrong, I like DBZ quite a bit. But other than that I dont like alot of modern series. It's all harems and... er... harems. It's hard to find series that are focused on story and character development instead of being focused on boobs and... pretty much just boobs. I think of things like Iria (the one that got me into anime), or Armitage the 3rd (both are fairly old now) and if I mention those, nobody knows what I'm talking about. Or some not-so-old ones. Good luck finding anyone that's ever heard of Library Wars (a particular favorite of mine, but talk about niche...).
Just... bah. Yeah, sorry, I'm totally ranting here... well, venting really. Too much of this frustrating crap over far too long, you see. It's no wonder I'd rather play freaking Q*Bert on a virtual arcade cabinet, than interact with other gamers.
