The Total War Wiki has the details on a new Patch 4 that's now available for Total War: ROME II, Creative Assembly's historical strategy sequel. The notes are pretty short, in that way that War and Peace is, so here's a useful summary: "This update includes major AI improvements related to the constructions of new buildings, food supply management, creation of armies, technology researches and tactics used during battles, making the AI more organised and challenging. Further tweaks and improvements have been made to the diplomacy, missiles, melee units and much more." They are not through yet, as they say Patch 5 will enter public beta testing next week, offering "further technical optimisations and improvements to gameplay, balance and usability."
