Most single-player games that have an multi-player or online component also have an offline mode for single-player use. This game should have been a combination of a basic single-player mode (campaign style, maybe with goals to accomplish, etc) in addition to a multi-player mode that would allow for online play with other cities. At least with a single-player mode you know there is a part of the game you'll always be able to play, long after the online components have been discontinued. Conceptually, the online mode sounds pretty intriguing but, obviously, was poorly executed.
