Ooh, thanks. New question on that very last point;

Does that mean that there is not a wide variety of Pokemon species living within Union? What I'm imagining now is that the city is populated primarily by humans, obviously, but that the "starter" species are very prevalent, and Pokemon of other species occur mostly in the wild and are brought into the habitats within the cities by Trainers. Is that about right?

...Also just occurred to me: are the livestock in the agricultural tower Pokemon (Tauros, Miltank, etc.) or do we have non-Pokemon animals?
