Same with Emerald in relation to Ruby and Sapphire and Crystal with Gold and Silver, the only way you'd play Diamond/Pearl over Platinum is if you specifically wanted to use one of the Pokemon that Platinum doesn't have natively on your team, like Skuntank.
Diamond and Pearl's only real "flaws" are minor niggles, like the surfing speed, the in battle dialogue automatically scrolling past the Pokemon name when asking you if you want to switch with the game still set to switch, the lack of Fire type Pokemon, etc.
>>51830886>I think there is a genuine attempt to shit on the GBA-DS era of gamesThere is one of those, it's mostly done by XYfags who think that people bashing the old games is something normal and not something that only started happening because XY were legitimately bad games.
