    It sounds like your User context also needs a Game entity. Note however that this is not necessarily the same Game entity which is the root of the Game context. These two bounded contexts may have different ideas of what a Game is, and what properties it has. Only the identity ties the two Game objects together.

    User Context
    {
        Aggregate Root User
        {
            Identity;
            Name;
            OwnedGames : List of Game value entities
        }
    
        Value Entity Game
        {
            Identity;
            Name;
        }
    }
    
    Game Context
    {
        Aggregate Root Game
        {
            Identity;
            Name;
            Owner : User value entity
            HighScore : int
            TimesPlayed : int
            ... A whole bunch of other properties which are not relevant in the User context
        }
    
        Value Entity User
        {
            Identity;
            Name;
            // No OwnedGames property, in this context we don't care about what other games the user owns.
        }
    }
