I'll also just readily admit every time I hear "but the new ones are relevant to the Plot" I roll my eyes hard because
Ah yes the riveting Plot of a Pokemon game
Environmental storytelling in these titles is far better imo
Also, for as much as I adore Koraidon
It and Miraidon aren’t really “legendaries” or at least they don’t feel like it. They’re just paradox forms of a common pokemon (Cyclizar). The likes of Lugia and Ho-Oh have actual legends around them, haha
Gotta disagree there, feels like the 5 birds have a lot of setup, ESPECIALLY the Johto birds. They both get their own dungeons and plenty of NPC dialogue.
