My #Genefunk game is set in the city of Pacific Point, which is essentially Night City from Cyberpunk using a fan map someone uploaded to RPG.net.
However, after getting a gaming PC a couple of months ago, I've been building a cyberpunk-inspired city in Cities Skylines. Using a mod in the workshop, you can create a workable map of the city in .png format. Had I had this setup a few months earlier, I may have custom-built the city in the game and used the exported map alongside screenshots.
@blaster218 you should call this Night City Skylines. I dig it Choomba!
