Session analytics are fundamental to understanding player engagement, but finding the right balance is crucial. I'm curious about how you measure session quality versus quantity - is longer always better, or do you optimize for session frequency instead? What metrics do you track beyond just time played, such as actions per session, progression per session, or session abandonment points? How do you identify the optimal session length for your game genre? Do you use techniques like dynamic difficulty adjustment or timed rewards to influence session duration? What indicators suggest that players are staying too long (burnout risk) or leaving too soon (lack of engagement)? How do you handle differences between mobile and PC gaming sessions? I'd appreciate hearing about experiments or features that successfully extended average session time without hurting retention.
