• Looking at the timing, I'm thinking there might be seasonal effects at play. Has this 30% increase been compared to the same quarter last year?

Why it matters: Seasonal fluctuations could explain the churn increase. Expected answer: Yes, it's been compared and the increase is still significant. Impact on approach: If seasonal, we'd focus on year-over-year trends rather than quarter-over-quarter.

Why it matters: Identifying affected segments helps narrow down potential causes. Expected answer: The increase is more pronounced in casual players. Impact on approach: We'd focus on features and onboarding experiences tailored to casual players.

• Thinking about recent changes, have there been any significant updates to the game in the past quarter that might correlate with this increase?

Why it matters: Recent changes often trigger unexpected user behaviors. Expected answer: A new difficulty curve was implemented last month. Impact on approach: We'd analyze the impact of this change on player progression and engagement.

• Regarding measurement accuracy, has there been any change in how first-time player churn is calculated or tracked?
