I am not new to Sim City, but this version has me puzzled...
When I start a game, I zone out the Agriculture and low residential areas with a few commercials and about only 10% of residentials and 1 square of agriculture will develop... and the RCI indicator shows they all have demand (well commercial doesn't really).
If it's in demand then why is the rest not building up? unless the above the RCI means not needed....
