According to Siliconera, Final Fantasy Crystal Chronicles: My Life as a King for the Nintendo WiiWare Service will included extra downloadable content, which will come at a price.

So what will players be able to purchase: races. If you want to recruit Yukes or perhaps Selkies, cough up some money to construct a building for them. Also, additional costumes will be available for Leo and Chancellor Chime. Though Square Enix hasn’t announced the price for the downloadable content, but we imagine it shouldn’t be more than 500 points…hopefully.
