In requirement 1b, what does “play value” mean?

For the purposes of this merit badge, play value is the reason that someone plays a game. Most people play games “for fun”, but what does that mean? In checkers, for example, the fun may come from competing against a friend or family member. In a sport the fun may come from working together as a team. When you think of play value, ask yourself what makes a particular game worth playing.
