Personally, I'd get both and rise of the samurai too (an add-on to Shogun 2). The battles are rather different and naval power plays are far more prevalent role in your campaign. Fall of the Samurai has a different take on the economy too, although they look similar on the face of it. Set 400 years before the dramatic civil war depicted in SHOGUN 2, the 'Rise of The Samurai' campaign is based on the Gempei War, a conflict between six legendary clans of the Taira, Minamoto and Fujiwara families. Rise of The Samurai is a brand new, independent campaign for Total War: SHOGUN 2.
