Successfully tested a very rough BoB map of 577.6 x 408 km covering the areas shown in the pictures.

You could even go bigger. My current Slot map is 825.6 x 601.6 km. But the problem with a map that size located in Europe is the enormous amount of detail that has to be achieved with the static objects. Numerous cities, towns, villages and farms. You're talking about a project that will last you a fair bit of 2 years, which is what it took to complete Slovakia.
