Square-Enix mentioned some of the neat-o bonuses you can get by carrying around your Square-Enix games at the event.
– If you have Dragon Quest Monsters Joker you can get a rare monster
– For Final Fantasy Fables: Chocobo Tales (Chocobo to Mahou no Ehon) you can get a rare card for Pop up Battles
– For Seiken Densetsu: Mana Mobile there is a special item that changes the color of your pet
Specifically for Final Fantasy Fables: Chocobo Tales there a number of pop-up cards have been released in Japan. While there haven’t been any announcements about how to get these cards in North America there are plenty of DS download stations scattered in stores that could be used as distribution points.
