    It is known that a user's personality influences the genres of games they prefer, but the relationship between personality and game mechanics has been less investigated. However, discovering such relationships is important for understanding how adjusting game difficulty based on users' personalities can enhance their intrinsic motivation. This paper investigates the relationship between Big Five personality traits and difficulty adaptation methods constructed using static difficulty curves in a VR Kendama game. The results revealed statistically correlation trends between specific personality traits within the Big Five factors and indicators of intrinsic motivation-namely, enjoyment and self-efficacy-across three different difficulty adaptation methods. This suggests that by utilizing the derived correlations, appropriately selecting difficulty adaptation methods when users with specific personality traits play the game could simultaneously enhance their enjoyment and self-efficacy.
