SimCity is very much a product of its time. They went with the dominate development paradigm of the late 80s and I guess they've stuck with it because the game has sold very well. Why mess with the cash cow? If there ever is another version released, maybe the features of the competition will spur the project managers of SimCity to expand into the modern era.
SimCity as I knew and loved it is completely dead. The last entry to the franchise was a mobile game released in 2014. I can't see the series being much of a cash cow for EA anymore.
