It's been working for me for the most part. Just had a few issues with my latest city, but I think it's because someone abandoned their city and all of the crooks are heading to my city to rob and steal in copious amounts ;/
So now I'm just creating private regions and inviting friends in that I know won't abandon and know what they're doing LOL.
The overlay maps are so perfect and addicting to watch your water, electric, sewage, busses, etc travel down the roads to service the city. So far I've been pretty successful with my cities.
