What are the most frequently visited sites?

The most recent versions of this simulation, MS Flight Simulator 2004 and the newly released MS Flight Simulator X, cater to pilots, would-be pilots and people who once dreamed of being pilots alike. Less a game than an immersive virtual environment, it can often be frustrating, complex and difficult due to its realism, but it can be rewarding for the skilled flightsimmer at the same time. The flying area encompasses the whole world, to varying levels of detail, including over 20,000 airports. Individually-detailed scenery can be found representing major landmarks and an ever-growing number of towns and cities. Landscape details are often patchy away from population centres and particularly outside the USA, although a variety of websites offer scenery add-ons (both free and commercial) to remedy this.
