I don't know. I think there are always people who say "The one *I* started with was *BETTER!*" no matter which franchise bạn view. There probably were Pokémon những người hâm mộ as early as vàng and Silver that đã đưa ý kiến "But I liked Red/Blue/Yellow BETTER!"
I'll guess it didn't get noticeably bad till Gen III though. That's when things really started to change. The original Gameboys were gone, graphics significantly upgraded (not just color), a whole new region far from Kanto and Johto, a whole slew of new game features like berries and contests, villains besides Team Rocket, etc. If people weren't upset over the new color and 100+ Pokémon in the Pokedex, I'm guessing they were bởi the time Ruby/Sapphire rolled around.
No, it started on gen 3. Everyone was kids back then and were still looking phía trước, chuyển tiếp to thêm Pokemon. I don't know anybody that hated gen 2, but only now people are hating other generations after gen 1.
Idk I was a baby back then, but I'm pretty sure it started sometime after the 2nd gen. I played ngọn lửa, chữa cháy red and tim, trái tim vàng and I thought they were pretty good. I kinda like the new games better than the old ones not just because of the better graphics. I like the new pokemon, they are mát, máy làm mát in my opinion. I hope I don't start a gen. war for saying that.
