GP Madrid is under way and it is looking to blow the doors off previous records. As a GP Madrid opens with over 2,225 players gathered to play Legacy. It will cause numerous headaches for organizers but the attendance is not entirely unexpected, yesterday they were reporting pre-registration over 1,500. This astounding attendance is only further surprising due to the fact that the event is Legacy. The previous attendance record for a Legacy GP Event was held by GP Chicago from last year with 1,230.
