Google Play Games on PC aligns with Google Play Games Level Up's cloud save guidance for cross-device play.
In addition, your cloud save solution must work across platforms. This way a player can freely switch between PC, Android, and iOS without losing or resetting progress.
We also recommend providing a seamless restore experience using Google Play Games Services (PGS) v2, leveraging the platform identity provided by Play Games Services's platform authentication to identify a returning player across Play enabled devices. The Recall API lets you associate an account with a Player ID without restructuring your login system.
