DP issues:
>Suffocating Pokedex that was smaller than the last two games not counting FRLG, which also has the same problem but at least was trying to be faithful remakes of the first game
>Despite the small dex they thought it should be like 30% Water types with other types getting like two or four options tops. Masuda's Water boner hurts this franchise
>Tied to that, all the brand new evolutions are post-game for some retarded reason. At least have half-and-half
>HM bloat, but this is a problem with GSC and RSE too, just it affects their late games more while Sinnoh's midgame is when this starts being a problem
>Laggy, slow engine which mindbreaks zoomers
Other than that it's an improvement over RSE in every way. Most of these issues are mitigated/fixed in Platinum, though that game has a few problems of its own due to breaking DP's pacing. Honestly not as bad as how Emerald breaks RS' pacing. Platinum deserved a real remake that polished some of its issues and reverted some things back like Fantina after Wake just to spice things up but instead we got Masuda's worst remakes where the only cope is "b-but they play good!"
