Adapting to the player in order to keep him interested

EA filed the first patent on a Dynamic Difficulty Adjustment (DDA) device five years ago. The game publisher has revised and refiled the patent many times since then. The most recent patent was filed on October 6, 2020, and was released on March 25, 2021. EA’s new DDA system, which uses AI from the cloud, updates the game’s complexity depending on the player’s engagement to extend the length of a gameplay session.

According to the patent, the DDA device “can perform automatic granular complexity modification,” which should be “undetectable by the consumer” in some situations. The framework creates “a game retention projection model” based on “historical consumer experience data with respect to one or more video games” to determine the estimated length of a gaming session.

The algorithm changes the game complexity to the player by integrating past user experience data with the game retention prediction model.

EA recently filed another patent to circumvent update and update times, enabling players to get right into the action even quicker.


In other words, if a particular boss is giving you a headache after a few attempts, the machine can make things simpler so you can advance in the plot. By finding the boss less difficult, the system anticipates that you will continue to play the game rather than abandoning it.

“Software developers typically desire for their software to engage users for as long as possible,” the patent reads. “… often, games that are too difficult or too easy will result in less enjoyment for a user. Consequently, the user is likely to play the game less.”

EA was recently awarded the patent, although it has already used similar methods in games such as Madden, and other developers, such as Shinji Mikami on God Hand and Resident Evil 4, have already used this form of device in their games.

If adaptive difficulty system is used for single-player games like Dragon Age or Mass Effect, it should be okay as long as the user can turn it off. But if you apply it to games such as FIFA and Madden in a multiplayer environment, it quickly becomes tricky and for that reason EA has even been taken to court. Clearly, in PvP games, the result of a match should not be influenced by AI and computer-controlled systems.
