An event ticket is your "pass" to an event. Unlike other conventions, where you may or may not get into an event after a long wait, Gen Con features event tickets that guarantee your seat at the table or a venue. An event ticket allows you to participate in various activities, such as playing a game, attending a seminar, or seeing a band.
Have you got your ticket? You're all set to attend an event!
Most, but not all, events at Gen Con require an event ticket to participate, not just your badge. You will need a badge in order to acquire your tickets. You can buy tickets for friends, too!
Most tickets have a small cost ($2) associated with them, but some are free and some cost more depending on the associated costs and demand for an event.
