Rome 2's Caesar in Gaul expansion campaign has a problem with recent history. Unfortunately for Caesar, The Creative Assembly has established a pattern of releasing novel and systemically distinctive follow-ups to their major releases. Shogun 2's Fall of the Samurai campaign was a fascinating collision of Age of Rifles technology and doctrine with the fading samurai way of war. The Peninsular Campaign expansion for Napoleon: Total War likewise tried to combine traditional Napoleonic warfare with the guerrilla war and counterinsurgency campaign fought across the Spanish countryside. Both these campaigns (and arguably, Napoleon: Total War itself) tweaked the core Total War game design in exciting ways to cover more specific conflicts and challenges.
