This morning's Nintendo Direct presentation revealed how Bravely Default's microtransaction system will work. Players can pay for optional "Sleep Points," which are also available through regular play.
Players can hold a maximum of three Sleep Points at any time, which they can use in different ways, including reviving a downed character. Sleep Points will automatically regenerate while the game is not being played, or purchasable for real money in the form of potions.
An extended Bravely Default demo will also be available on the 3DS eShop on January 2. The demo will be an exclusive mission that's not included in the main game, and playing it will net players StreePass tags and items when the full game launches.
Bravely Default will be released on February 7 in North America.
