Something I enjoy about playing video games is how I am able to create my own stories while simultaneously playing the game.
When I was a kid and did not really understand everything I was supposed to do on a game I used to create my own stories in my head for the world I was in. For example, I remember playing Super Mario Sunshine on Game Cube and getting stuck on the first level of Sirena Beach. I used to pretend Mario was hired for the cleaning of the place and would clean all the weird muck thing that was everywhere. Then, after cleaning, instead of actually engaging in the level’s mission, I would leave the place and do something else. I got used to doing things like that for every game I played, especially if it was an open world and I could just explore around for as long as I wanted to (that’s one of the reasons I love open world games so much).
There are even more possibilities for creating your own stories in multiplayer games. For example, Nerd3 makes his own mini games and rules inside GTA V with his friend. In the video below their only goal is to successfully jump across the buildings with a car. This has nothing to do with the actual GTA V game story or missions but they use what the game provides to create their own experiences.
I believe this is something that makes video games unique and that I cannot do with other mediums, like books and films. Of course we can imagine background stories for characters or imagine them in situations other than what we read or watch. However, we cannot do it simultaneously to reading or watching, since we are focused to what is happening in front of us.
