Videogames are an environment that usually gives a high level of agency to the user. Computer agency has two major conflicts with the concept of agency present in real life and narrative. The first main conflict is about life and death. Videogame death is very different from traditional death. That means that if, during the game, the character dies, it will resurrect later.
Players know that they can always restart the game from scratch or resume a previous saved game.
Generally, when a narrative character dies, there is no way back. The second major conflict has to do with agency. GON can be restarted and each game session can be completely different from the previous, allowing the player to experiment many possible actions and behaviors. So, actions become trivial, and the feeling of agency can lower. The player can easily become lazy and take decisions without considering consequences, because it is always possible to start over.
