DDA stands for Dynamic Difficulty Adjustment, which is a mechanic within a games code that can adjust certain gameplay aspects to make it more difficult or easier for players to carry out certain actions. In the context of FIFA, DDA is a controversial topic that has been the subject of much discussion within the gaming community. While EA Sports has denied the use of DDA in FIFA, Madden, and NHL Ultimate Team matches, there have been claims that it is present in the game. DDA can affect player inputs and add an element of randomness that goes against the concept of competitive gaming. While DDA is generally fine in its traditional form, which only affects AI-controlled enemies or obstacles, its implementation in a multiplayer title like FIFA 23 is problematic.
