The Dynamic Difficulty Adjustment (DDA) is a system introduced in Crash Bandicoot 2: Cortex Strikes Back and then also implemented in many later Crash Bandicoot platforming games, designed to help players struggling with a certain level or section of a level. The idea was to make the game easier for players who were struggling, without making the game easier for better players who would like a more challenging game. The DDA was thoroughly planned out by Naughty Dog in Crash 2 and 3, but a very minimal version of it is included by later developers in Crash Bandicoot: The Wrath of Cortex, Crash Bandicoot: The Huge Adventure, and Crash Bandicoot 2: N-Tranced.
