G, who is sitting here beside me in a coffee shop, says I just have to mention this marvelous artifact of the 21st century. Cow Clicker is a game which was invented to satirize the sheer pointlessness of many games. You click on a cow and it moos. You gain a point and you can invite friends to be part of your pasture. That's it.
To the bemusement and eventually frustration of the game designer, it became a breakout hit.
People don't understand satire, says G.
It's now over, because the designer decided the cows would vanish in a "cowpocalypse" and would be raptured away. De-moo.
