To comprehend player behavior effectively, several key metrics are essential: engagement metrics such as session length and frequency of play provide insights into how often and how long players are interacting with the game. Retention rates, often tracked at various intervals (such as Day 1, Day 7, and Day 30), reveal how well the game keeps players coming back over time. Player progression data, including levels completed or skills acquired, helps assess player satisfaction and motivation. Additionally, in-game purchases and virtual currency usage highlight monetization patterns and spending behaviors.
