I don't know how many people have played this, but I found it to be a pretty entertaining game, and very educational, like Civilization.
CivCity Rome
City Life
It's different, I'll give you that. It doesn't feel quite like Sim City, but I did enjoy it. My criticism comes from the architecture on some of the buildings... bleh. The small amount of city buildings is also a bit annoying. You'll have 4 cookie cutter buildings all lined up next to eachother...bleh.
The best thing about the game? The fact that you can zoom into it at "walk level", and see your city's skyline. It reminds me of when I use to play Sim Copter in my SimCity 2000 cities.
