Focus on the Game Mechanics, Not the Game
While games are an important and fun aspect of gamification, the main focus of gamification should not be the games, but rather the game mechanics. Game mechanics are what makes gamification so motivating and flexible; depending on the goal for implementing gamification, the games may vary considerably, but the most basic game mechanics will have the same purpose: to engage the user. Because of this, when companies evaluate the impact of gamification, they should not be focused on how many points the user achieved or whether or not they won the game, but rather on the increase or decrease in their productivity after the installment of game mechanics.
