An important aspect missing in typical flow models is that in order to produce enduringcommitment a goal should correspond to something truly valuable. For example, while the goal ofshooting a maximum number of spaceships in your game of Space Invaders may be clear, it doesnot satisfy any real needs. Therefore, playing games, however enjoyable at the time, if continuedlong enough will eventually leave you with the feeling of having wasted your time. One way gamedesigners try to overcome this limitation is by creating a sense of “epic meaning” (McGonigal,2011), i.e. situating the game action in a narrative context which implies that something truly greator valuable is being achieved (like saving the world from alien invaders).
