>>53742084> Gen 2 didn't benefit from Crystal, Gen 3 from Emerald, Gen 4 from Platinum,Most of Crystals' changes were QOL that would have been added earlier if not for Gen 2's troubled development.
Emerald's story probably benefited the most but that's only because Ruby and Sapphire had two separate villains so Emerald was able to to join them.
haven't plaid Platinum so I can't say what story improvements it actually made.
>Gen 5 from B2W2, Gen 7 from USUM?aren't those sequels
