  ### implementation
  * devrait on utiliser gamers plutôt que users ?
  
      _eventuellement on pourrait etre utilisé dans des app autres que des jeux, mais comme on a basé toute la comm sur le jeu, va pour gamers!_
  * devrait on utiliser l'authentification Basic pour identifier le gamer ?
  
      _ca ne marche que por les cotc login, puisque pour facebook il nous faut un token.
  en revanche, une fois "identifier", le login return in id/token a utiliser dans Basic/Atuh_
