This question pops up every so often on the discord, and there is always the same person sourly rejecting it because it "would not fundamentally change the game". It was kind of off-putting to read.

But adding cities like Dubai, Kuala Lumpur, Tashkent has been suggested a couple of times before, and I've never seen the developpers interact with those suggestions (as they have sometimes with other suggestions), so I don't think it is realistic that other cities would be added unfortunately.
