Yes. They are extremely different. They both take place in the same region, but many things have changed. Different Pokemon, different Elite Four, differen Battle Frontier, different mass outbreaks, different story line in some places, and you can go to the distortion world in Platinum, but in Diamond you catch giratina in Turnback Cave.
So it's very different in many more ways than listed above.
yes he will be standing in the same place not in firered, leafgreen, emrald, sapphire or ruby just platinum diamond or pearl...............find out yourself
Its the sequel of diamond and pearl. Its the same region but it has addition things like walking on walls and distortion-like things.
Well if it's the same as diamond or pearl, you would defeat the galactic building in Eterna and rescue the bicycle shop owner and get the latest model! =]
doesn't matter, the only difference is the rare Pokemon (palkia for pearl and dialga for diamond) and you can only get stunky on diamond not pearl and you can only get Scorpio on pearl not diamond. Other than that they are both the same and both as good. hope i helped!
Right after it learns Thunder, because Raichu can't!
