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?
Best Answer
You need the new games, as those are the only way to get Plaza Tickets (you get them for accomplishing various goals in each game - they are like rewards for gaining achievements).
Once you have at least one of the new games, you can start earning tickets, and then can exchange them there for various outfits or hats for your Mii (they change apparently daily, but I don't know what clock they use.)
