That’s probably something a person who has no clue about Pokemon could say. You underestimate how many mechanics older games contain, since like half of them are not obvious for casual players. Although I am not sure about gens newer than IV (Diamond and Pearl is the most recent I’ve played), since I haven’t played them. But most people agree that the best games were around that period (Gen IV, or V), and they only become worse over the years.

Gameboy studio in 30.

Pokemon Infinite Fusion is in fact made in RPG maker and is imo the best Pokemon game out there.

It’s a standard RPG but replace the equipment with animals. Done.
