SCS Software felt it was necessary to clarify about the content of American Truck Simulator. All future customers will directly have California state ready to explore with a US truck. Nevada US state will also be available as a free update to download for everybody on the release date. Another DLC map expansion will be free on a future date : Arizona.
The only differences between the Standard and Collector Edition are merchandising items shipping with the most expensive. The game itself won’t have any difference. In the long term, SCS Software will sell more maps expansions to cover USA, but maybe also Canada, Mexico and others depending on the commercial success.
