I have seen this asked many times but I'm not sure what the answer is here. Anyways I bought fall of the samurai before I bought Shogun 2. And it always says I own shogun 2 in steam library but of course I am only able to play FOTS when the game opens. Am I missing something here? How would I go about purchasing the Shogun 2 Part when it says I own it? Any help thanks.
