I think a fundamental assumption in this article is flawed: "The most popular games are still pretty simple, but mid-core games like strategy simulator War Commander are gaining steam. Some people who used to be content clicking FarmVille crops have moved on to more complicated games."

So called "mid core" games on Facebook are generally male focused war/strategy titles. Most Farmville/Cityville, etc. players are women. They haven't "moved on" to more complicated games. They've just grown tired of the same formula.
