Hmm. Well, simply put, it would be a massive project. The sheer scale of it would make it utterly different to everything Pokémon has done before, as well as extremely difficult, and would necessitate throwing out a lot of the established gameplay and storyline conventions. As cool as it would be, I think that such a mammoth project would be impractical for a cartridge game, and that the details would suffer as the designers attempted to cram everything in. Now, for something like an MMORPG, it might be more practical, but to my knowledge Game Freak have never expressed any interest in MMO Pokémon (besides, I just plain don’t like MMORPGs). Maybe for a strategy game it could work? But no, for a traditional Pokémon game, I just don’t see it happening, and I think the attempt would likely be ruinous.
