I really like this mapping of game characteristics to PKM. I was particularly intrigued by the fact that those five characteristics don't include competitiveness. Take Stardew Valley, for instance. That is a game where you play as a farmer who's taken over their grandfather's old farm. So there's no competitive nature inside of that game. And I would argue to have the most healthy relationship with your own PKM system,. You could have a competitive nature with other people in the community if you're the type of person that arrives on that.
