>expand to South Kalos, region becomes a hexagon (6th generation)
>18 gym leaders, players can choose the order they fight them. only 8 are required to participate in the pokémon league
>Pokémon League starts like Pokémon Colosseum's Realgam Tower or Galar's (in a tournament that develops like the Battle Dome or PWT)
>Only after said tournament are you able to face the Elite Four. Capitalize on the 4chan order pasta (Steel, Fire, Water, Dragon, Princess)
>All megas available (including ORAS ones), dynamax forms become other kind of mega forms that only last for three turns (because this changes their HP, while normal megas keep their HP)
>Zygarde lore is only post-game, with Malva trying to revive team Neo-Flare and find what happened to Lysandre. Very cinematic. In ZX, Xerneas and Kyogre fight Zygarde, in ZY Yveltal and Groudon fight Zygarde. when the player fights Zygarde, these legendaries show up in the background and their moves can hit the player mons.
>2nd round of the Elite Four capitalizes on Megas and Items. Malva is replaced by Flannery in the Elite Four, with a Mega-Camerupt. Siebold gets Mega-Sharpedo, Wikstrom gets Mega-Aggron and Drasna gets Mega-Garchomp. Diantha's team gets an overhaul: Goodra, Ninetales, Milotic, Mawile, Dragonite and Mega-Gardevoir (like Alder, she gets a strong pokémon representing each of the E4's types) — like BDSP, 10 levels higher
>Third round against Elite Four (even 10 levels higher) opens up the Grand Room in the Battle Chateau, where you can freely battle against Lance, Blue, Red, Steven, Wallace, Cynthia, Volkner, Alder, Iris, Diantha, Leon, the champion challengers from Alola, Mustard, Peony and Rose (all level 100, only held items during battle, EVs, IVs and Natures perfected)
