# Overview

Reality Asset Data (Data Asset) refers to data assets that represent content within the game and are essential for sandbox mode.

This allows you to configure and modify parameters for your actors, game mode, skins, etc., at runtime.\
Most systems are designed to use RealityAssetData to make the game as modifiable as possible.

Once in-game, you can create derivatives of existing data assets, and then modify them directly within the game; they will be shared over the network by the server and saved.
