Sengoku walkthrough video tours feudal Japan

Sengoku, the Paradox strategy title that puts players in the role of an eager Japanese noble attempting to rise to the level of Shogun, is due for release on 13 September.
To give you an idea of the sorts of things you’ll be getting up to in the game, the publisher has released this walkthrough video. In it, you’ll learn the key to success in feudal Japan is having multiple wives (wait, is this right?)
Sorry, the key is to appoint advisors who don’t want to kill you and to successfully plot against your enemies. Having a large military force doesn’t seem to hurt, either.
If the video tweaks your interest, you might want to have a read of my full Hands-On piece about the game.
