In an interview with Rolling Stone, Activision revealed that they had an exploratory patent for videogame matchmaking (placing players in multiplayer games) that would push players to monetize more. The method involved selecting matches for players that would make them more or less difficult depending on a players monetization pattern, and what the algorithm thought would make them monetize more. For example, if a player had yet to purchase, the algorithm might put them in a more difficult match against someone who had to make them feel as though purchasing was necessary to succeed. Activision did state that this system is not implemented in any of their current games and was purely an “exploratory Research and Development project”.
