Total War: Shogun 2 - Rise of the Samurai basically gives you another campaign similar to the original for the game.

I have played the original several times but could barely get through 'Rise of the Samurai' once. Total War: Shogun 2's new standalone expansion, The Fall of the Samurai, attempts to give us a glimpse of how Japan's transformation actually took place – and a chance to rewrite history while.
