Microsoft Files Patent for Adaptive Video Games

Microsoft filed a patent in June describing games that reconfigure in real-time using generative AI, even measuring the player's facial reactions. The document is still under review, and the company has not indicated whether any Xbox titles are already utilizing this technology, leaving an uncertain horizon. The concept aligns with procedural generation but operates with a reactive logic.

Pending Patent and Uncertain Horizon

Microsoft's patent is still pending, and its approval could take years. The company has declined to specify whether any Xbox titles in development are already using this technology. Under these circumstances, it is not expected that games based on this principle will emerge quickly, and the lack of operational details suggests a delay before active deployment. At this stage, even the arrival of a game capable of automatically rewriting itself remains difficult to anticipate.

An AI System That Rewrites the Game According to the Player

The described system involves generative AI that modifies the game based on the player's actions. It would take into account exploration, interactive objects, and frequented characters to rewrite or rework elements in line with observed preferences. Microsoft even mentions measuring facial expressions and reactions to refine the offering, with the ambition of transforming players into co-creators and varying the experience according to each session and individual. Specifically, if a player lingers in an area, the AI could generate quests, lore, monsters, or NPCs while removing content deemed unengaging. This new content would then be evaluated by the AI, which could integrate it into the main storyline. The entire system is designed to operate in real-time, tailored to the user, providing a distinct experience from one player to another. The patent thus aims for games that rewrite themselves based on interactions.

Difference from Classic Procedural Generation

The principle refers to procedural generation but differs in its timing. In Minecraft, entirely new maps are born from a seed code composed of numbers and text, which determines the location of mountains, caves, resources, and biomes, with each seed producing a different map. No Man’s Sky applies this process to its solar systems and planets, and titles like RimWorld, Dwarf Fortress, or Wildermyth use it for characters, the world, and storytelling. This approach is generally preventive, with elements created before the player interacts. The concept described by Microsoft would be reactive, generating content after the player's actions. The analogy with Pandemic Legacy illustrates this logic, where permanent modifications by players result in a unique version at the end of the game.

Mixed Reception and the Role of Human Creators

Generative AI in video games elicits mixed reactions, with some players turning away from titles that employ it. Award-winning games like Baldur’s Gate 3 and Clair Obscur: Expedition 33 have, however, utilized it in certain respects and have been highly rated by critics and players. Even in this context, developers and writers would still be necessary, as AI relies on pre-existing rules, stories, characters, and a world to learn how to produce new elements.
