For games, would you implement to security or to usability?
I plan to create a game that is largely online-based via mobiles.  I have in my mind how I would handle authentication for both a very secure standpoint (login, credential creation, etc), and also from a very usable standpoint (device authentication, client based, no action needed).

Since I am the only one in my development team (lol), I am interested to hear your input about this problem.  In my mind, I would like to implement to usability due to the lackadaisical nature of gaming, and how impressed I have been with services like scoreloop (who dont require and/or pester the user for login / password / account generation).  But it also brings a certain amount of uncertainty and lack of control to the user.

For a game, what is more important to you?  Or is there an implementation you can think of that is a marriage of the two?
