I totally agree with these.
Add depth does not necessarily mean more complexity for end players. Look at simcity 4 again, the background formulas are many, but most are not shown directly for players. In SC many things are interconnected, and evey change will alter the equlibrium. However, in CS, they are not. No matter the wealth and the health, the Cims will always die at same age (correct me if I'm wrong), the traffic does not have much effect, and the tourist system is broken.
One of the core problem for CS depth is that Cims and RCIs are not divided. Currently Cims are only divided by education, but not by wealth. This imposed great difficulty for in-depth simulation. And is not likely to be ever modded, or officially improved. I understand ultimately the budget is behind this, so I can only hope with enough support the problem of over-simplification will not happen again in CS2.
