The Streetpass Plaza recently updated to include some new games and in the process, it has added a new icon called "Exchange Booth".
When I try clicking on it, it doesn't do anything and there's no help or information on it.
How does it work? What is it used for? Do I need to have one of the new games (Mii Force, Flower Town, Warrior's Way, and Monster Manor) for it to be functional/useful for me?
