>>58468889Zygarde was written after the fact, its complexities were designed in 2015 after ORAS even came out. That's why 100% form had to be shafted as a sidequest in Sun/Moon. None of that shit was planned for XY as shown in the Teraleak, which is why Z-A needed to happen in the first place because otherwise the fucker wouldn't have fully gotten its development without it. And even now what we got in Z-A is nothing but retroactively trying to squeeze the damn thing into the XY story, it's not elegant at all
Johto's a traditional setting and they already had tied its lore to Sinnoh with HGSS and the Arceus event. They're effectively sister games like Kanto-Hoenn are. It would've been redundant to just do "the past" again even if they were likely planning to replicate the Platinum-HGSS release but likely realized the fact they did PLA to be different in the first place means they shouldn't just "keep replicating the past" so while I'm glad for Z-A attempting to fix XY's wrongs and incompetence, it also did so in a pretty backhanded way by effectively telling a brand new story where the only through-lines to the original games were Team Flare-related and nothing else
