We have a community of 135 000 people in our group, and we want to develop an application integrated to FB that will allows them to get informations regarding our community. So this is not really a game. But the only way to do that is to create a game inside Instand Game and to publish it and after to promote it for our community.
So is it allowed to do an application for Instant Game that is not really a game ?
