Question

Now the problem is i h

Answer 1

You can merge the tables leaving TenantId as NULL for records you wish to not be Tenant specific.

Games

Id
TenantId
GameName

The you can query that table in a Join with:

...
FROM
    Games
    INNER JOIN UserGames ON
        UserGames.GameId = Games.Id

WHERE
    Games.TenantId = @tenantId OR
    Games.TenantId IS NULL

This will save you the trouble of ensuring that the Id is unique between the tables, unless you are using a UNIQUEIDENTIFIER for the Id.
