It's easy adding a bunch of content to pretty up your Life as a King, but the latest details for the new Japanese additions are anything but cosmetic. For a price of 300 Wii Points, Infinite Tower is a tough dungeon with plenty of infinitely awesome treasure to find. The Library (200 Points) allows you to teach species-specific abilities and includes an extra dungeon.
Finally, Castle Reform (100 Points) lets you change adventurers names and adds the Temporary Estuary Dungeon. Three content-heavy updates for a grand total of 600 Wii Points. Nothing superficial there .. except that bikini for Chime and new clothes for King Leo -- 100 Points each. Well, lives of kings can't all be explore'n and build'n.
