Arizona is not just more of the same. Our work on California and Nevada started well over two years ago, and even though we kept polishing the game all through the development cycle, the map design process and the roads were largely based on our older generation of tools and prefabs. Meanwhile, our tool-chain has matured considerably with the ETS2 team's work on Scandinavia and Vive la France, and for Arizona, the ATS team is using the power of the new modular system to put the road network together.
