ISL is a standard league format competition with the champion being crowned by topping the table at the end of league play. The league has a light RP element and is focused on the traditional races of the Old World Warhammer universe although exceptions are made if they do not upset the overall balance. Games are tentatively scheduled for Sunday to maintain a manageable pace that allows for opponent scouting, although the weekly fixtures may be played on any date agreed upon by the respective coaches.
