I- look man, this remake was made with I think exactly me as the target audience. If you're gonna remake Diamond and Pearl exactly and not Platinum, this is how you do it. I miss the level curve and expanded NPC teams of Platinum, sure, but not enough to not have an absolute BLAST playing this remake. It expands on D/P just enough for me. It coexists with Platinum to me, would you rather have elements like a better level curve and slightly different progress, along with a slightly different story; or would you perfer to play DP with modern QOL improvements from the past 14 years of Pokémon, like better (though forced) experience sharing, different outfits, and full 3D instead of the 2.5D of the DS games? The choice is yours.

Also you can use a Mew on your team for the main story through an old save bonus, and god DAMMIT that's my favorite Pokémon and I don't get to use it like, ever.
