>>55075733>The intent was likely to make everything feel unique and with its own niche.Gen 1 barely has any niche diversity. Every single every Grass type is BadExeggutor, every Ground and Rock type is BadRhydon, etc. Normal is special because you can either be BadTauros or BadSnorlax!
Psychic and Water are the only real types with actual variety in function and that's mainly just because Water is half the dex so inevitably some uniqueness will slip in and Psychic is so broken you can do anything with it.
This isn't really meant as a criticism of the games either, the gen 1 (and to a lesser extent 2 and 3) games were very clearly designed as single-player RPGs first where the early pokemon would be weak and shitty and objectively worse than the later Pokemon, e.g. Electabuzz is just a better version of Raichu in practically every way. But it's still dishonest to claim Gen 1 Pokemon had diverse niches or that they were really even trying to do that.
