>>25306488I think it did a lot of things really right, like vastly improving the story and characterization of RS, some improvements to the region like underwater trainers and the Scorched Slab being an actual dungeon, and a ton of little detail or QoL things like flying to routes, Soar, ways to speed up Surf, symbol encounters, and the DexNav. But several things wrong too, like stripping down some side stuff, a handful of dungeons being dumbed down heavily like Granite Cave, Sky Pillar, and New Mauville. It doesn't help that the post-game is basically RS' poor post-game with RNG mirage islands and the literally copypasting XY's battle facility leaving a sour taste for anyone who spent a lot of time with the Maison in XY the prior year.
Personally I thought the maingame was one of the most enjoyable in Pokemon, but once you hit Delta Episode a lot of the games flaws become more apparent and it kinda falls apart.
Oh and Delta Episode is literally the dumbest shit in the series, the only good part of it was the hype as fuck Deoxys fight they spoiled before the game even came out on the official site and trailers, and they used DE to insert the Emerald Champion Wallace battle.
