I recently got Sim City and have since created 3 cities. Two were practice cities that I've since given up on and now I've started a new region with my friend.
Basically, in each of the 3 cities I've created, I've ended up with exactly the same problem. I have extremely high residential demand (all three wealth types) and extremely high industrial demand. At this point though I've run out of space and building are already upgraded to medium/high density. At the same time, I keep getting residential blocks and high density industrial building being abandoned. I don't understand, why are they abandoning when there is such high demand?! I don't understand what it is I'm doing wrong. Can anyone help?
