Weather engine, injects real weather conditions and meteorology into the simulator, I use it in another simulator (Prepar3D) that just like ETS2 started without this tool, however with its introduction the simulator went to another level of reality.

I think it would bring the game a new dimension to players facing the severe weather conditions in Europe, it would no longer be necessary the winter modifications that are already released every year, and if it is a paid mod I would not think twice and buy it
