Being your own contractor you can rip off yourself.
I suppose I don't have to explain what the game is about. Your progress is shown from a 3D top-view, which you can rotate or zoom in or out on. Make sure that roads don't have dead ends, try to connect them to neighbour cities so your population can increase (or they all can flee). Keep your people happy by building a library, university or a park, etc. Increase your business by building a harbour and airport.
At first don't make your city too large with long roads and tracks, the maintenance costs will kill you. Tip: Switch off 'Disasters', I hated to see how an alien attack destroyed half my city!
The graphics are detailed en looking good, everything looks best when zoomed out. Sound is ok.
