What little i understand of gamification, the game must not be ready made out of the box, it must address the specifics of what you desire to encourage, the specifics of the users - or you not only don't accomplish the goals gamification is designed to encourage, you also risk loosing the interest of the players, as a vanilla game comes to be seen as of no value to the player.
A gamification must not be ready made out of the box. What do sucessful game designers think?
