>>32180831I don't have the time to make multi-post textwalls today sadly, but to talk about the biggest one and the one that fucking drives me insane that ORAS doesn't have it, the improved double battle system from Emerald.
In RS and ORAS, all double battles are hardcoded as such and. without exception in the former and with several multi battles as the only exceptions in the latter, always have exactly two Pokémon on the opponent's teams.
Emerald completely rehauled how double battles work, and while there are some hardcoded double battles still, it's now possible to enter a double battle against two separate trainers who otherwise would engage you in two single battles, if you walk into their line of sight at the same time. Sometimes the maps are created so a double battle is unavoidable, other times this creates the choice of whether you want to do them one at a time and avoid the double battle or take on both at the same time and get a double battle with three or four, and if I remember correctly rarely five, Pokémon.
The best-remembered change in the game that resulted from this overhaul is Liza & Tate going from the most laughably bad Gym Leader battles relative to their position in the game in the franchise to a decent battle with four Pokémon (even if three of them still die to a Surf), but these spontaneous double battles are everywhere in Emerald.
This overhaul was so good it's retained in DPPt and HGSS. That they went back to the old method in ORAS was fucking infuriating to me. It's the biggest step back you could possibly make with double battle systems. I know they dropped this improvement before ORAS because XY didn't have it either, but to not bring it back just shows to me that they completely ignored everything good about Emerald when designing ORAS.
And the only thing more infuriating than the devs completely ignoring ORAS is people defending it with "they're Ruby/Sapphire remakes :^)" like that's not a fucking terrible design philosophy.
