Player segmentation is essential for delivering personalized experiences, but choosing the right segmentation approach can be tricky. I'm curious about the criteria you use to group players - do you segment by playstyle (casual vs hardcore), spending behavior (whales, dolphins, minnows), engagement level, or skill progression? How many segments do you typically maintain, and how do you avoid making your system too complex to manage? What tools or frameworks help you identify meaningful segments automatically? Once you've segmented players, how do you tailor content, offers, or communications for each group? Have you found that certain segmentation strategies lead to better monetization or retention outcomes? I'd appreciate hearing about any segmentation experiments that surprised you with their results.
