I guess that there are many things that I do not know yet in SC4. Till this point I thought that Low Density Residential zones means the same as Low Wealth Residential zones. But I realized that it's not afterd examining the desirability data views. Can someone explain this to me? If I build a Medium Density Residential zone does it mean that it's gonna be Medium Wealth Residential zone? If not (I guess), how does the wealth of a certain group increases? Another thing, what's the difference between the Cs and the Co? There are commercial services and commercial offices. How can I build services and how can I build offices? And the same thing here, how can I increase the wealth of that particular commercial zone? Agricultural industry (I-Ag), is it the low density industrial? So what is I-D, I-M, I-HT? How can I build those various industrial zones? I haven't understand thses stuff yet! Please help... Thanks!
