>>33320113Most of what made those games good came from the base games. The things you listed are just sprinkles on top.
The features people praise the games for, like Platinum's physical/special split came from the original games. Being carried over to another game still counts as an advantage that game has. HGSS copypasted Platinum's Frontier, but it still counts as a positive for both Platinum and HGSS. If all these things don't count, then Emerald and Platinum would be shit for copying almost everything RS and DP had to offer and only bringing a facility as something new to the table, and FRLG and HGSS would also be bad for having most of their major changes come from RS and DP too.
You also keep mentioning ORAS being casualized, but the movesets for all the trainers have been improved. Back in Emerald, most trainers' Pokemon had horrible moves, like Steven's Aggron using Solarbeam. Just like how HGSS improved on GSC's teams, ORAS did the same to RSE's by improving their movesets or outright replacing some, like Glacia. The only exception is Liza and Tate, who miss out on their Emerald mons.
