The community platform is a series of functionalities in game that allow you to communicate with other players across different Atelier 801 games. It offers two main features: a universal account for all Atelier 801 games, and the ability for various features to transfer between games, such as friends. The community platform was released on 10 September 2013.
Your friendslist is available between games, and you may talk to friends on a different game than you are on.
Your tribe also is available between games. As this is not always desirable, it is not uncommon for people to create alt accounts to join a different tribe on a different game.
