I like to get out this is not meant as a suggestion. I am genuinely curious if one could design the perfect city or zone for your main or supergroup what would it be or look like?
My zone is a mix of the Imperial City of Praetoria and a bit of Cyberpunk 2077 for my SS/Invul. mutant Brute Saturn Man. All the tech and bright future. Flying cars, parks, jet pack citizens, tubes transports like in Futurama. However with the worst using cybernetics and advanced weapons to commit crimes. It would have the usual villains, Sky Raiders( higher level with cool tech upgrades) and Crey. But with new enemies that look like Servetors from 40K to replace the Freakshow, wild mutations and random solo villains.
Like I said, it is not meant as a suggestion, but a random thought made from curiosity while playing. Now a zone can be anything including suburban areas or mystical forests.
