Structure for multiple game support

[player-guest]

So I see you are working on the multiple game support. Then let's talk about the implementing.

I was finished the gitadora and popn music part and using the structure similar to yours. Then I add a simple json api to the main server, and using ButterflyUser to do the authentication. So one thing I done was make the game profile not relate to ButterflyUser but only relate to a Card. Then the user can bind theirs card to a user.

Do you have any suggestion?
