>Every improvement Platinum (aka the definite edition) made is completely ignored, except for some tongue-in-cheek references from NPCs, this includes the updated Sinnoh regional dex, the Battle Frontier, updated and improved teams for (nearly) all trainers, especially the important ones, early Rotom + formes, the Distortion World
>Map is a 1:1 recreation of the DS games which turns the game into one long cramped hallway
>Despite Platinum being completely ignored, Looker is shoved into literally every single story beat, aggressively holding your hand and extends the play time by several hours just on his own by spewing unnecessary bullshit as per usual
>Several chokepoints from the original (first Mars battle, Barry battle in Canalave, last Cyrus battle) are heavily nerfed without taking into account that the games are likely easier anyway, making the battles laughably easier
>Exp Share is still forced
>Underground gets the ORAS Safari Zone treatment (aka completely neutered, it's just a small cave with 2-3 hallways)
>It's just the fucking Battle Tower again
>No Gym Leader rematches
>Pal Park was not cleverly made into something new like a secondary, post-game Safari Zone/Wild Area, instead it's just a sign saying "The Pal Park project has started"
>Glameow is missing from the regional dex somehow
