Second Life – the world of “almost infinite possibilities”: it is easy to navigate inside, to use and explore it for instance as human, as animal, as robot or even as dragon. However the environment of Second Life always reflects either the image of the city or the landscape. One easily will find lots of differet aspects of themes, like suburban residential areas, areas wasting space like a classical 'urban sprawl', city of themes, simulated giant cities or romantic parks and wilderness.

Using the metaphor of the city seems to be a simple method to generate a familiar image for the users, and allows the virtual alter egos to navigate in this new world of cyberspace.
