I think the series "No Game No Life" covered this best -

"There’s no way to know the rules or the goal, yet there are 7 billion people making whatever moves they want. If you lose too much, or win too much, there are penalties. You can’t pass your turn, and if you talk too much, you’ll be ostracized. There are no parameters and no way to even know the genre. This world is just a crappy game."

- Perhaps a tad melodramatic, but still...
