Understanding Disengagement From Competitive Multiplayer Games: An Exploratory Study of League of Legends

Competitive multiplayer gaming environments, specifically within the context of League of Legends, present unique psychological challenges that frequently lead to player disengagement.

• Player disengagement in competitive multiplayer games like League of Legends functions as an essential, involuntary mechanism for managing the stress and frustration of high-stakes team environments.
• The shift from leisure to 'forced exhaustion' is primarily driven by restricted player agency, where the necessity of team coordination and volatile match outcomes override individual control.
• Coaching structures act as critical mediators that help players regulate playtime and manage the emotional demands of team-based competition.

An Investigation of the Test-Retest Reliability of the miniPXI

The miniPXI serves as a short-form instrument designed to measure player experience, yet its utility for longitudinal or repeated evaluations remains limited.

• The miniPXI is reliable for tracking high-level metrics like overall enjoyment, appreciation, and Net Promoter Score, but it lacks the psychometric precision required for complex dimensions like immersion and mastery.
• Multi-item frameworks such as PXI, PENS, GEQ, and AttrakDiff consistently outperform the miniPXI in capturing nuanced player experience data.
• The study evaluated the miniPXI’s stability over a three-week interval using a sample of 100 participants across four distinct game genres.
