Shogun 2 requires only a fraction of the micromanagement of Civ5. Shogun 2 is smooth sailing in comparison. Civ5 is a chaotic mess in late game with many cities and units that cannot be renamed or grouped into armies (no stacking allowed etc). Shogun 2's ship building, movement and ceued end-of-turn movement actions are all a pain to deal with. Using the interface to find/control air power in Civ5 is a chaotic confusing cumbersome mess. Shogun 2 has similarities in being very slick and streamlined in gameplay and interface (both games have areas that are lacking badly. I have almost 300 hours of Civ5 and 600 hours of Shogun 2.
