From countless hours making games, it is because games can be fun in many different ways yet it is hard to make a fun game. One of the most common way projects fail is that they are trying to be fun in a variety of ways but not achieving player enjoyment in any of them.

I used to work with a great designer who used to say the goal was to take the un-fun out. That actually is a more actionable goal.

Perhaps it is easier to identify what's commonly considered un-fun than what is widely considered fun.
