If you are familiar with FarmVille you know that it has a reward system called "achievement ribbon." The game gives you special ribbons for unique achievements (like planting 1000 crops). The panda does not play FarmVille anymore. The game feels like it gets more and more pointless and stupid as the game goes along. Ironically, the game's simple expectancy and reward system keep you from playing the game more. Consequently, it also teaches patience in achieving goals.
The panda adopts a similar reward concept by launching My Wish List. Whenever a sensible life goal is achieved by chance or by choice or whenever a wish comes true, he affirms it to the world. He hopes small things like this can help him be more motivated in playing "the game" - the game of life.
