Pros: Easy to learn, and fun to play!
Cons: Gets boring
Comments: Really fun to play when bored.
Uh, there are two possible things wrong with this. On the one hand, if the game's only con is that it gets boring, yet is fun the play when bored, then, as the commentator astutely points out, the game must be REALLY fun to play! On the other hand, why would you play a game that, if bored, will cause you to become bored (or even more bored) as a result of playing it?
