Basically that means by focusing on only Japanese shores they can "immerse" in the culture of the period, and it can be "a thing of beauty".
"When we begin development, as a team we immerse ourselves in the period and the setting that we are trying to bring to life in the game," said Lead Designer James Russell in a Sega , reports .
"We develop features that reflect the battles and the military & economic dilemmas of the time (as well as making for great gameplay)."
"On the campaign map this means we fold in the importance of honour, treachery, clan & family, and many other aspects of being a warlord in feudal Japan. Of course, we need a completely new set of agents and agent abilities too."
"On the battle side, special, historically accurate, hero characters can help turn the tide of battle. We’re also giving siege mechanics a complete overhaul: Japanese castles are very different from European castles, and we’re working hard to make the layouts look convincingly Japanese as well as playing well," he continued on.
They plan some "very exciting things" for Shogun 2's multiplayer but won't be discussing that just yet. Napoleon: Total War introduced an online feature the fans have wanted for a long time - multiplayer campaigns - and this is likely to return.
"We really want to make Shogun 2 a thing of beauty, and the most immersive Total War game ever. We are focusing on pushing gameplay depth and polish rather than raw ‘size’ or scope: doing more with less," noted Creative's Russell.
"Internally, we are calling these things together (beauty, depth, polish and immersion) the Zen of Total War. We are absolutely committed to making Shogun 2 the most breathtaking Total War experience ever."
Naval battles will remain in Shogun 2, with ships laden with archers and samurai warriors ready to board opposing vessels and clank blades together. You'll also have land in sight to help better orientate you, with ships driven by oars and not the winds.
Shogun 2: Total War will release exclusively on PC.
