According to Doctor Who, time is “a big ball of, wibbly wobbly, timey wimey stuff”.
I like to think that he is correct, especially in games. Nothing is necessarily linear, it is up to the creator, the player, and the observer. How would you perceive time as each person? How would you alter time as the creator of the game? Do you make it necessarily linear, or can you warp it without your players noticing? As the player, would you play according to the linear narrative of the creator or would you make your own timeline in the game? As the observer, do you see the player going according to the timeline suggested in the game? Or do you see the player in the game time space or in time in the real life?
