Here’s an angle on the fundamental reason for why we play games: They are about personal development, learning about ourselves and about the world. This may not be a new angle, but I haven’t heard it stated this explicitly. Instead I have heard people say stupid things like “games teach hand-eye-coordination” which is true, but also bullshit because why would you spend this much time training your hand-eye-coordination? No I claim that games teach import life lessons, and that that is the fundamental reason why we play games.
I’m going to talk about video games, but this is also about games in general. Why do kids play with dolls? Because they want to learn about family life. (or about conflicts when playing with action figures) This is not explicit learning like we learn from a teacher, but you act out situations and adjust your behavior depending on how your play partner reacts. Why do we send our kids to football practice? Not because we think that they need to learn the valuable skill of kicking a ball into a net. No it’s because we want them to learn about working in teams and about pacing themselves and about playing fair and all that.
The things we learn are obvious in those scenarios. It’s well known that it’s important for kids to play in order to figure out how to act in the world in a safe environment. But I claim that the same thing is true for video games, and my example will be Super Mario World.
