In digital games, it is unclear how players experience game-unrelated thoughts (GUTs), whether GUTs should be encouraged by game designers, or how it may impact player experience. We ran an initial study to confirm whether GUTs are common (50 of 100 participants reported experiencing them). We then collected 840 minutes of gameplay data from 12 participants playing games they: (1) found relaxing, (2) lost track of time in, and (3) spent most hours playing. Eye-tracking data and experience sampling were used to contextualize a phenomenological analysis of gameplay data. We identified four themes encompassing gameplay, GUTs, and gaze behaviour: these provide a foundation for future research and game design incorporating GUTs.enmind wanderingdaydreaminggamesplay experienceConference Paper
