Gamification of training is often equated with rewards. But extrinsic rewards will only take you so far… they can sometimes feel gimmicky and short-lived, and need to be replenished (which can get time consuming and expensive). 

But if your training is designed to engage the learner’s intrinsic drives, progressing through it becomes its own reward.  That kind of engagement translates into more focused attention and reaching learning objectives more effectively.
