I’m currently writing a rules text that is written from the point of view of your character. So instead of being addressed from the designer to the player, like:
When it is your chapter, your character is in the spotlight. The story bends toward them. It’s your coin to flip. Other characters can figure prominently, and should, but in the end it’s about your character, and what happens to them is your call.

It’s a weird voice! It feels oddly intimate. For a long time I’ve been inspired by the notion of Dosmukhamedov-style character agency (the idea that characters in fiction have their own voice, and their own needs and desires, basically), which this emphatically is not, but I think having your character tell you what to do with them suggests a certain mind-set for play and a certain sort of strange intratextual relationship between you and your tiny little character.
I’m sure other games have done this but I can’t think of any! Lots of fiction that has a game character speaking directly to the reader/player, but for rules text I’m drawing a blank.
