A quality game that is worth buying despite it's flaws if you are a city building enthusiast.
The MegaStructures are a great feature that encourage you to make numerous cities with varying specialties.
KEEP IN MIND: There is a known issue with this game where it slows down over time as well as when your city gets extremely large. This should not be a surprise, however, as a city wth 250,000 citizens with jobs and traffic requires more caculations then an empty lot. That being said, there is some "work" that needs to be done to work around a few known issues where the game becomes really slow and choppy when left running for extended periods of time. (A quick google search will resolve those issues.)
Also, as with any city game, if you have an older graphics card, a slow processor or a lack of RAM, you will have troubles with a sprawling metropolis of 250,000+ citizens.
Though it does lack the "driving mission" feature of SimCity 4 Rush Hour, this game is a superior rendition in almost every sense of the word to SC4, is highly moddable, gorgeous looking and comes with a solid sound track to boot. Resource management, city-to-city trade, a very diverse and yet easily managed Supply and Demand system, traffic concerns and the need for things like Holidays, Hotels and Food makes this a more detailed and realistic Sim City without the old technology and feel of Sim City 4 nor the various drawbacks of SimCity 5 (or Origins or whatever the hell they called it.)
A great pick up for a city building enthusiast.
Coupled with the fact that I got platinum for dirt cheap because I owned CitiesXL 2011, it was a must buy.
Suggested Purchase Price: $10 or less.
