I just want to make sure, the task you have to do cannot be fictional, like pushing a button every day at the same time? Like on a spaceship, you have to push a button. It must be a real world task?
Fictional elements are fine, and even encouraged. Some of the games in the example list include embellishments - there's a lot of fantasy elements in Stardew Valley, for instance. It's just the mundane task itself that needs a basis in the real world.
