I get it’s the first, but not everyone is nostalgic with that generation in particular
Hats off in mourning to those nostalgic for DPP whose remake got needlessly butchered and got nowhere near the level of treatment HGSS did. It bugs me beyond words that they've shown they can have overworld encounters for The Underground but somehow, that's not allowed on the main map. Meanwhile, they had to remake Yellow again to have a buffed up Pikachu and a riding feature.
That like... every major franchise in the 2010s, I swear. I'm exaggerating and relying on my unreliable memory, but this decade feels like the decade of "Hey 70s/80s/90s kids, remember X? Wanna see us do it again?"
It is frustrating because Pokémon is one of those franchise where every generation has its fans. Lucario, one of the franchise's biggest successes, is a Gen IV critter who was promoted no earlier than Gen III.
I feel like I've pretty much become immune to the nostalgia drug, hence why I've been extremely critical of many things I was passionate about as a kid. Main series Mario, spinoff Mario games, Spyro, Sonic and more have not been spared from my views. Pokemon is no exception to this and I'm especially harsh towards it because I love it so much. Not having to be held back by rose tinted lenses has allowed me to view and enjoy alot more games by my own choice. I have zero nostalgic background with Dragon Quest, Shin Megami Tensei, Monster Hunter, Digimon, Plants VS Zombies and more. Despite that, tons of my time in recent years has allowed me to enjoy those and be more observant of their evolution or pitfalls.
It also helps that alot of things I follow are either indie games or Japanese media that's more niche in the west, since I get exposed to alot of newer and fresher ideas from that angle.
For example, Disc Creatures is an extremely retro indie monster collector that's cheap, charming, heartwarming and something I highly recommend and it's getting a sequel in Disc Creatures World that's a massive glowup. If I spent all my time whining about Pokemon and taking no action, I wouldn't have known about such a great game.
I guess what I'm saying ultimately here is that it doesn't hurt to try new things. You know, something Pokemon also preaches with the idea it's okay to go out on new journeys and make new friends rather than being stuck in one place.
