The gaming industry is huge, and it can keep its audience consumed for hours, days and even weeks. Some play the same game over and over again — and occasionally, they even get out their 15-year-old Nintendo 64 to play some Zelda.
Now, I am not a game designer. I actually don’t even play games that often. I am, though, very interested in finding out why a game can keep people occupied for a long period of time, often without their even noticing that they’ve been sitting in front of the screen for hours. I want my apps and products to affect my visitors in the same way.
