The product description at Drivethrurpg says "Land of the Samurai is a stand alone RuneQuest game, designed for those of you who enjoy a huge pile of reality mixed in with your fantasy."
That is total false advertising. It is not stand-alone. It does not repeat the game mechanics needed to play. This is only a supplement. You must also have the regular Mongoose Runequest rules.
I thought I was buying a complete game. Instead it is just a sourcebook.
What a rip off!
