There's a fuckton of geometry, textures and mechanics that a good remake of Sinnoh would require, and SS just didn't have enough of anything to make the development of all that trivial.
>>43183950>Dynamax is stated to be Galar-onlyIt matters not. Megastones were stated to be exclusive to Kalos as a result of using the ultimate weapon, they're shards of pokemon crystalized by the blast.
Then ORAS came and retconned them to be meteorites.
>>43184084If anything, because dynamax is just about "power spots", they can introduce them anywhere. I don't know if int he end they were caused or not by eternatus' shards (it is said that it was stealing their energy to recover though), but at the end of the day, USUM just retconned Z-crystals to be shards from a necrozma that exploded in a different dimension.
