Supercell aims to create games that are remembered for years, contrasting with the trend of casual games being seen as short-lived 'snack entertainment'.

It's important to choose meaningful actions for measuring user engagement; simply tracking app opens can lead to misleading retention metrics.

Measuring retention is critical; if you don't have a product that retains users, you shouldn't focus on growth yet.

Supercell has a reputation for killing around 90% of the games they develop, which is a strategic choice to maintain high product quality.

When product teams focus solely on metrics like engagement or dwell time, they risk neglecting qualitative aspects such as content quality and user satisfaction, which can lead to long-term retention issues.

Tracking customer retention is essential; it helps you understand how many users continue to engage with your product over time, which is a key indicator of success.

Supercell's approach to innovation involves disrupting themselves to stay ahead of competitors, ensuring they continue to create unique gaming experiences.

The social-first approach addresses the challenge of retaining player attention by fostering friendships within the game, which keeps players engaged long-term.

Be cautious of measuring retention over too long a time period, as this can artificially inflate your retention metrics and mislead you about user engagement.
