We will never stop your game. In case of reaching the game's maximum player limit, players can continue to play the game.
Players, who joined the game after the limit has been reached, will be marked as visitors, which will allow them to join the game, but they won't be allowed to complete any task.
If you upgrade the player limit, visitors will be automatically converted to full players.
