Founders Editions And Dlc

Hi, I’ve been playing the founders edition since March on Xbox, but I don’t want to buy the full game as I never use any other routes other than British ones. Is it possible to buy DLC and use them with the Founders edition?

 

I would presume u will need the whole base game before getting any other dlc

 

The Basegame includes GWE / RT and NEC. So i think what JasonARJ3125 says is correct. That you need to upgrade to that package before you can go and buy WSR or any of the other DLC´s released.
