Oh darn - Microsoft changed their web pages AGAIN! ugh.

   Anyway, before the big latest reorg of Microsoft, they _HAD_ an
   Indie developers program for XBox.... 'til September '15.

   And in the documentation they had a fascinating, detailed
   overview of the types of illusions you have to create in order
   for your game to not be rejected by Microsoft.

   One was a few paragraphs explaining in great details what is
   allowed and what is not allowed in the character the player is
   controlling.

   I remember, for example, that you couldn't have your character
   "break the fourth wall" and turn around and start talking to
   you, for example.

   Man, I wish I saved that page before they zapped it. It was a
   deep look into the philosophy required behind FPS and XBox
   gaming philosophy in general.
