Its based on our idea of an american city . Although its got , for example , cars that may resemble New York police cars , if you look closley you will see that the police badges etc on the cars are not actual copies as we are not into infringing copyright. They are are own design but they seem to work.
Likewise even the fonts used are ones we have obtained specially so when we use them they don't infringe copyright.
Its quite a big city so I would expect it could form the set for many videos without featuring the same street twice.
Also because we have total control of the city - if you want your own huge posters or banners on any particular building - no problem. Just tell us which!
