>The overworld is pretty much 1.1 and looks awkward in the SWSH style
>Only 500 Pokemon which is mostly Gen 1-4 with very few new gen mons. Gen 1-3 starters and legendaries removed because they don't fit Sinnoh
>No SWSH compatibility
>Underground is now a Wild Area clone. Raids are done there. Secret Bases are surprisingly well done with the ORAS gym feature, but mining is dumbed down
>No trainer customisation
>Camp returns, curry replaced by Poffins. But it's the exact same minigame
>Contests return and remain mostly intact. The dress up is now a photo decorating contest and the dance section has really awkward animations of just the model tilting and moving
>Cosplay Pikachu returns along with a Cosplay Eevee
>Y-Comm returns but League Cards are removed
>New Gigantamax for more Kanto and Sinnoh mons, but they mostly replace the removed Gigantamax
>Dynamaxing shoehorned into the plot, with some bs about it originating from the distortion world
>Game Corner and seals removed, Great Marsh is now a route
>Rotom Watch replaces Poketch and HMs
>The post game is just the Battle Tower and Battle Zone
>Two-hour episode involving Giratina. Distortion World is just a hallway
>Eternamax for Dialga and Palkia and acts as a raid with Lucas/Dawn, Barry and Cynthia
