Click Machines

Some people argue that Zynga’s signature games — FarmVille, FishVille — shouldn’t even be called games. As Nicholas Carlson of the Web site Business Insider wrote: “They are click-machines powered by the human need to achieve progress by a predictable path and a willingness to pay small amounts of money to make that progress go faster. They are not ‘games.’ ” But you could argue that games like FarmVille are in fact just the logical end of gamification: gamified games. They have the appearance of games, they inspire the compulsions of games, but for many people they are not fun like games.

I think Diablo was successful because you had to click a lot. But Zynga takes it one further.
