City size is still very restricted though as I understand it. I was interested initially but all the problems put me off. Bro In Law has it and has had endless problems with game saves/server issues etc.
I only play offline and it's really good, the issues I'm having are traffic, budget/resource management & specialisms (so every major element aside from population growth really)
There was large issues initially but they was fixed in patches and updates and the introduction of the offline mode was added, I find it enjoyable and often screw up with over taxing or not enough police or fire coverage.
