# Data And Persistence

- [@ao\_serialize](https://docs.allout.game/data-and-persistence/ao-serialize.md): Select fields for scene, Inspector, and JSON serialization.
- [Save System](https://docs.allout.game/data-and-persistence/save.md): The save system provides a key-value data storage system for persisting player progress and preferences across sessions.
- [JSON Serialization](https://docs.allout.game/data-and-persistence/json.md): For saving more advanced data structures, you can serialize them to JSON and store them in the Save system.
- [Economy](https://docs.allout.game/data-and-persistence/economy.md): Economy APIs let you create custom currencies (coins, gems, XP, etc) and automatically persist them for each player across sessions.
- [Cross-Game Products/Data](https://docs.allout.game/data-and-persistence/cross-game-products-data.md): If you have multiple games that share the same data (e.g. a hub world and minigames) you can link them together automatically using the parent game system.
- [Editing/Viewing Player Data](https://docs.allout.game/data-and-persistence/editing-viewing-player-data.md): You can view and edit save data you've written for players at any time from the creator portal!
