What is a roleplaying game ?
First, let define what is a game!
A game is an activity where you seek entertainment, but you can also seek competition, like in e-sport.
You can play Starcraft for fun or to win, even to live if you earn enough money.
So, you always learn something in a game because you try to achieve something.
But, a game can be more or less competitive depending on what is at stake.
