Difficulty adaptation based on individual condition setting in multiplayer games. Game experience (left) can be optimized by balancing the game performance (right). – Left: The initial game experience under nominal conditions relates to the skill level of the opponent and is non-optimal for differently skilled players (squares). Optimal game experience is perceived by the players when the condition adapts the difficulty towards the players’ skill level (circles). – Right: A common initial game performance state consists of a conditional task difficulty and its corresponding player specific game performance (square). Player specific difficulty adaptation can balance the game performances of the two players (circles)
