You can diminish almost any game to a laughably low level by reducing it to its bare essentials: Harvest Moon's focus is manual labor, Brain Age is portable homework, and Animal Crossing is about paying rent. These games defy their lame concepts and successfully maintain an interested fan. Similarly, while herding livestock may sound like a thankless chore, Flock's delightful style and brilliant puzzles will charm and engage folks willing to game outside the box.
