Photoshop :: Sort Of 16 Bit Effect

I am trying to replicate the following pictures. What I want to do, is take an image of a city skyline, and make it look like it was from the classic streets of rage games. The video game pictures below are from streets of rage. Take a look at the city buildings/skyscrapers.

How can I do this as quick as possible? I was hoping there was another way than creating rectangles and making rows, then duplicating those rows! Plus it's really hard for me to see a city design like these in my head.

I also would like to take an image of New York for instance, and make it look exactly like the streets of rage buildings. How can this be done?
