Heroes Die.

Dystopian earth where 'actors' travel to an alternate fantasy world and broadcast their adventures for entertainment. Dual game modes where you are trying to manage your career on earth and run exciting adventures in the other world. The dimension hoping tech is obviously super expensive and controlled by the government so you'd have to thread the needle of doing what you're told or risk getting "cancelled."

You could make bad but exciting choices like murdering a king that would get you big ratings (in the story actors behaved so badly in the fantasy world that the term 'aktir' became synonymous with demons.) Anything sensational or exploitive would be worth big bucks but also make you tons of enemies and ramp up the difficulty of future adventures.

Couple ways to design the game, either create a new player character and just reference the book events, or play as Caine himself and go through his career up to the point of the books.
