I’ve been doing some thinking about how I headcanon the Unova region and a few things, such as how the Nimbasa subway system is underfunded and understaffed. In Japan, being the manager of a subway is a big thing, and their subway systems are great and fantastic.
Unova, however, is based on at least part of the US. And American subway systems are... Not good. A subway system in Johto or Kanto would be a terrifyingly stark contrast in quality, though Ingo and Emmet do try their best to make the NSS as top quality as they can.
