Quick answer: Replay storage per release surfaces gameplay length and engagement. Tracking median replay duration and per-game-mode trends informs design.
Replays = engagement. Storage is the proxy.
Per-game-mode duration
Median replay length. Trends by release.
Player retention via replays
Players who replay are engaged. Track replay starts per session.
Storage cost
Per-month replay storage. Predict cost.
Compress old replays
Replays >30 days compressed. Storage reduced.
“Replays are operational data. Inform design and operations.”
If your game has replays, the storage and engagement metrics are easy wins. Track.
