Grand Theft Auto IV's Liberty City.
Liberty City is a city that is riddled with drug dealers, pshycos, robbers, and everything in between. The city is just about the size of the well known city of Los Santos. The city lies atop of seven different islands, six of which are connected by bridges the last one lies to the south. The large city is also known for it's trade mark symbol being the Statue of Happieness. From a distance you can see the city is covered by a thick smog much like New York and other large moderen cities.
Liberty City is the main immigration capital of the 3D universe (A reason why Niko Bellic came there) and that is why it's harbors are always busy with people getting off of the boats that dock there.
