I've played about 40 hours of this game usually when I was too tired to focus on more mentally strenuous games. It's not very difficult once you learn how to play the fun comes from military conquest and forming massive super countries, It was a fun experience just don't expect too much from it.
It's the same fallout game we know and love but with offline backup installers and no internet dependency. That being said it does have issues with optimization on newer gaming pcs but these are also present in the steam version it's due to neglect from bethesda but can be fixed with mods.
