I am always interested seeing all the unique and creative designs game developers come up with for their city. My favorite architecture styles would have to be modernist, brutalist, and classic futurist.
After watching some beta game play footage of Mirror's Edge Catalyst, I completely fell in love with the design and layout of City Of Glass.
It has the right balance of modernist/futurist and brutalistic features! I would like living in that 'dystopian' world !
