>>56196888A faithful remake wouldn't have botched the underground (they just used it to shove new mons in with Pokémon Go type bullshit that doesn't belong in DP in the first place) or had party wide exp share that CANT BE TOGGLED OFF plus unavoidable Amie shit that intrinsically alters the vanilla experience. By the way the underground multi-player was unintuitive, glitchy, and made mine and my friends games crash multiple times. Never happened to me playing DP.
A faithful developer would have remade Platinum, not Diamond and Pearl, even if it was sold in two games anyway (they did this with HGSS integrating Crystal content) This should go without saying.
A GOOD remake should stay faithful to the vision of the original while retaining everything and adding additional features and content that feel organic to the experience.
