You sit down, ready to get in a few minutes of gaming. Hours pass and you suddenly become aware that you’re making ridiculous faces and moving like a contortionist while trying to reach that new high score. You ask yourself: Where did the time go? When did I sprain my ankle?
More often than not, these types of gaming sessions occur when you’re playing a great game. If game developers were able to characterize and add design considerations that facilitate these engaged states they’d create more enjoyable and better selling games.
