I've not delved into CSII too much, partly because i think it requires so much micro management as I mentioned.
Here's a YT that shows how deep of a rabbit hole you go down. At 3:34 mark, the content creator is placing individual buildings (not zones) and doing things that that seem to fool the game into accepting parking lots. Then at 9:50 (this is where the video is cued up too) he's placing individual stickers on a couple of buildings. Granted he doesn't do that for the next city block, but again it highlights the level of simulation you're dealing with - which is both amaziing, but also overwhelming.
That's just too much for me, I may give CS II another try but I don't think I want a city simulator that goes to that level of management.
