Defines the maximum number of people who can play the game at your server. Caps at 10 for normal players (6 for guests), 20 (16 before update 2.3.7) for those with verified accounts and 16 for people who purchased premium (effects of premium only last for a limited time). The default is 2, to suit the players who just want quick 1v1 matches with no-one else disturbing them. From update 2.3.7, guests have a cap of 6 players. In update 2.3.9, a new setting was added where you can host 40 player lobbies if you spend 1000 KR.
