Agreed with Gamerprinter. You can do cities with CC3, but City Designer 3 comes with a lot more tools and symbols to create cities. I tried CC3 when CD3 wasn't out yet, but CD3 is now my weapon of choice.

Doing height things, like with your city in the sacred forest, is going to be difficult. But that's going to be difficult in most software if you are creating a 2D presentation.
