““By March 2012, Zynga’s stock was flying high and the company was valued at over $10 billion. But by November of that same year, the stock was down over 80 percent. It turned out that Zynga’s new games were not really new at all. The company had simply re-skinned FarmVille, and soon players had lost interest and investors followed suit. What was once novel and intriguing became rote and boring. The “Villes” had lost their variability, and with it, their viability. As the Zynga story demonstrates, an element of mystery is an important component of continued user interest. Online games like FarmVille suffer from what I call “finite variability” — an experience that becomes predictable after use.””
