The Samurai Resource Pack is additional content that costs $19.99 and can be purchased from RPG Maker Web. The content was created for RPG Maker VX, but will work wonderfully in RPG Maker VX Ace. The content is also close enough to the graphical style of the RTP that it can easily be mixed and matched with the default content. If you're looking to give your game a Japanese feel then this might be for you.
