Comparison of Game User Experience Satisfaction Scale results across 15 participants for the assessment session (original version) and across 4 participants who opted for the training sessions (improved version), averaging 3 recordings per participant.^a

	Usability/playability	Play engrossment	Enjoyment	Audio aesthetics	Personal gratification	Visual aesthetics
Assessment session (original version), mean (SD)	5.399 (0.573)	4.925 (0.887)	5.363 (1.050)	4.783 (1.372)	5.544 (0.717)	5.422 (1.080)
Multiple training sessions (improved version), mean (SD)	6.053 (0.500)	4.965 (0.647)	5.583 (0.514)	5.708 (0.241)	5.528 (0.718)	6.028 (0.048)
Effect size (Cohen d)	1.216	0.052	0.266	0.939	−0.022	0.793

^aAll scores were, on average, higher in the training sessions than in the assessment session. This trend of high training means relative to assessment means is captured in the effect size, with the usability/playability and audio aesthetics subscales having large effect sizes (<0.80) [58].
