Underwater and Floating cities?

[Jerry246]

Has anyone had the thought of or consideration on including Cities in their games that were in impossible locations? Where you wouldn't expect a town or city to be located. Specifically one at the bottom of the ocean and one floating high up in the sky. both being based on the Cities of Rapture and Columbia from the Bioshock games.

They'd be both themed around water and flying types but rather than being along the coast/body of water or high up in a mountainous area, these cities were built directly into the habitats these pokemon types reside. On the Ocean Floor and amongst the clouds.

Has anyone though of for once, adding these locales as part of their regions?

I'm not sure if this is what you're exactly thinking of but I've got a town planned that sunk into the ocean due to a catastrophe that happened in the past. Its last resident still manages to hold on to the 7th Gym spot in the region (out of 8).
