>>23604791>Which evidence?Are you even reading? I already mentioned the fact that none of Yellow's exclusive NPCs exist in any of the other Kanto games. And before you say that they don't matter, that still doesn't explain why the old in-game trade couple in Cerulean City is still living in their house from Pokémon Red, Green, Blue, FireRed, and LeafGreen in Pokémon Gold, Silver, Crystal, HeartGold, and SoulSilver.
>Trading? With who? When? For what Pokemon?Absence of evidence is not evidence of absence. Trading and in-game trading is pretty much possible.
