DDA stands for "Dynamic Difficulty Adjustment" and 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 has been a controversial topic among players and content creators, with some claiming that it exists in the game and others denying its presence. EA Sports, the developer of FIFA, has stated that they do not use any scripting or DDA technology in FIFA, Madden, or NHL Ultimate Team matches. However, some players have reported experiencing unexplained changes in gameplay difficulty during matches, leading to speculation about the existence of DDA in FIFA. Despite the controversy, there is no concrete evidence that DDA is present in FIFA or any other EA title.
