フタリシロ (Futarishiro)

フタリシロ (Futarishiro) is a castle-building game set in the age of warring states. To win, you must build a castle that's harder to overcome that the opponent's. Perhaps you can build a moat, arrange a tower, store weapons, train soldiers, and prepare for battle.

It's difficult to build a castle exactly as desired, though, as you have to read the psychology of your opponent to get the castle tiles that you want and design your territory in the best way.
