Similarly, there are many situations involving games and work, that aren't gamification. So, you know what the most successful video game of all time is? It's Windows Solitaire, as you see there on the screen. 9 billion hours that people played this game in 2003. That was the latest data that we have, and that was a long time ago. Where do you think they play it? Much of the time people play it at work. It's something people do when work is boring. Gameification is about finding things that are not boring in work, and using game elements to enhance them. So, it's very different than just saying there's games at work, that's gamefiication or we're going to make work more game like.
