It is nintendo's devious conspiracy to make us, otherwise reclusive, gamers go outside and meet other people. But as far as story and game play go, there is no different. The fact that each version has exclusive pokemon.

Diamond is the most popular Pearl is less popular.

The Pokemon badge cases are different colours.

The pokemons, and the name of the game.

The legendaries? and the coulour x3

Diamond sounds much more manly.

that reminds me of the VG cats comic that came out at that time..........

The pokemons you can obtain and the name is pretty much all there is.

they just have different pokemon....i wish they just combined everything (like the emerald version)
that's what they did to platainum...

Pearl is to Diamond what Red is to Blue.
