I've been a little out of the loop ever since the second generation of Pokemon, but I understand Diamond and Pearl are doing very well for the DS. My question is.. does Diamond/Pearl ever allow you to visit other regions apart from Sinnoh? I remember Gold/Silver let players revisit Kanto after they completed all the areas of the Johto region.
Wouldn't it be a good idea (lucrative too) for Nintendo to release a game where players could start in any region they wanted then work through the other regions as they completed their own objectives.
I know there has been much debate over the production of a MMORPG with the same idea, but a simple DS game that allowed the player to explore all the different regions. All the pieces are there, it just needs to be made.
