I came across this video while looking up some SimCity info a couple weeks back. It’s a cool video that shows you the process of building a Megalopolis (Megaropolis) in SimCity on the SNES. The video is mostly played at 3000% speed of the gameplay. That combined with the awesome music playing makes this quite entertaining. The music sounds like some crazy techno, cyberpunk music but is actually the Dark Lich theme from Secret of Mana (SNES).
As you can see, the strategy seems to focus on the absence of roads and really dense zoning. Makes you wonder if the cities of the future will be this way?
