SC2K was made when they were still pure Maxis, SC3K was made when they were a part of EA, both are exceptionally great games. I used to re-make Canuck Cities in 2K and 3k, posting them to BBS's, I'm sure someone could find them still if they wanted. Off the top of my head, I did Toronto, Windsor, London, Kitchener/Waterloo, Hull, Ottawa, Halifax, Edmonton, Saskatoon, Victoria, Vancouver. Small cities and towns like Woodstock, Ingersoll, Kingston, etc. They were very popular for people to tinker with, I think I was 15 or so at the time.
Anyway, I grabbed Cities: Skylines. I have a few complaints, one of which is the lack of building diversity. Though modding gets around that very easily. Overall, it's like the days of 3K, where there is micromanagement, you can buy up neighboring plots of land to expand your city and watch just how great or screwed up things can get.
