I think the actual issue is that most gamers today are arguably not really gamers anymore. You've got the advent of online games, quantity over quality gameplay combined with the rising cost of living + the death of game rentals. There isn't really an incentive for people to fork out $50 or more for a unique experience when most games nowadays are designed to keep you hooked for hundreds of hours. I've probably played at least 100-150 games back in the day through rentals but your average zoomer / gen alpha will probably grow up playing exclusively minecraft / roblox and/or whatever game is currently trending. If those same people become indie devs, can you really expect them to make anything original? It's hard to iterate unique ideas if said Developer onlys plays a small handful of games.
There are still a lot of unique indie games out there, but they are getting increasingly harder to find in an industry that's beginning to drown in a slurry of slop.
Its funny I missed this response, because it actually does touch on something I feel is a problem... well, more than "touch on." You said it: a lot of modern creators have very few experiences.
And it's something that worries me, and probably contributes to the problem I've been going on about. Like it or not, most "creators" aren't really creative--humanity usually can't have an idea that's not suggested by something else first. And when your experience pool is limited, so are your ideas.
Heck, I've even experienced this first-hand. I've seen people, for example, claim that its impossible for First-person Shooters to incorporate swimming (there was a brief period of time where FPSes would avoid having you in water for long periods). Then I was like "Duke Nukem 3D did it and that was back in 1994" and it just blew their little minds.
One of the funniest interactions I had on that front: in a group, there was an argument about how "good" graphics have to be. Someone asked "would you play a game that had absolutely no graphics at all?" My response was: "yes, I would indeed play Zork." The guy ended up having to look up what that was, and from there was shocked to find out how compelling it was.
But again, mostly I think this is the problem. A lot of people have experienced only a narrow range of ideas, and its the rare person who looks and wonders "why does it
have to be this way?" And even then, it becomes a process of reinventing the wheel.
........... On this note.....
Recently I saw the first few seconds of
a Game Theory video that kinda proved my point. The video was about how "Mascot Horror is dying and being replaced with more psychological horror." His proof? Entirely that the Game Theory subreddit is now talking about that stuff more often.
My immediate thought was this showed the GT guys are not real gamers, because those kinds of horror games existed long before Mascot Horror, and indeed greatly outnumber it... but here is this moron, fucking
flummoxed that horror games that aren't about Mascots could possibly
exist.
He hadn't seen it, therefore did not know it was possible. Out of sight, out of mind.
