According to the documentation : The GameInstance exists for the duration of the engine’s session, meaning that it is created when the engine starts up and not destroyed or replaced until the engine shuts down. A separate GameInstance exists on the server and on each client, and these instances do not communicate with each other. Because the GameInstance exists outside of the game session and is the only game structure that exists across level loads, it is a good place to store certain types of persistent data, such as lifetime player statistics (e.g. total number of games won), account information (e.g. locked/unlocked status of special items), or even a list of maps to rotate through in a competitive game like Unreal Tournament.
