Competitors usually concentrate on one game or at least limit themselves to a certain genre. The tournaments vary in size and scope, some running several hours at informal locations, while others span multiple days and pack professional stadiums for championship events that can carry prize purses in the millions. Others, like the Madden event in Jacksonville, are smaller tournaments leading up to larger events later in the calendar year. The Jacksonville event was a regional qualifier leading to an October final in Las Vegas, with a top prize of $25,000. It was unclear how many players were in the mall when the shooting occurred.
