What you describe as targets over ‘4D states’ reminds me of Finite and Infinite Games by James Carse. For an example, playing a game of basketball with a winner/loser after an hour of play is a finite game. However, the sport of basketball overall, is an infinite game. So playing a specific video game to reach a score or pass the final level is a finite game, but being a ‘gamer’ is an infinite game, allowing ever more types of gaming to take place.
