After all the pre-launch hype about changing the face of gaming forever, the game was dreadfully boring -- you basically walk around and click on things. I described it to a friend as "FarmVille where you don't get your own farm." Sure, there was a lot of art; I think I had my pick of several dozen hairstyles and encountered hundreds of types of objects. They must have drawn thousands of art assets.
There is no lesson to take away here except that games live or die on their mechanics and depth. Zynga has shown us exactly how far you can go with pretty, social games that give you just enough little dopamine kicks to keep the window open.
