Representation and Frequency of Player Choice in Player-Oriented Dynamic Difficulty Adjustment ...
summary
Claim: shifting difficulty control to players can hurt player experience depending on how choices are shown and how often they appear. Method: controlled 3x2 within-subject study using Snake with 84 participants who each played 18 games, factors = embedded choices vs keyboard control and periodic presentation vs once vs constant. Results: embedded choices boost action-awareness merging and altered time but not overall harm; once is worse than periodic; constant can reduce clear goals, and embedded+constant produces the largest drop. Recommendations: design choice representation and frequency deliberately.
