INDIANAPOLIS - Days before the 50th edition of Gen Con kicks off in Indianapolis, organizers have announced a sellout. The event, which draws more than 60,000 visitors downtown and is one of the biggest conventions in the state, has expanded beyond the Indiana Convention Center and into Lucas Oil Stadium and nearby hotels.

A concert featuring Grammy-winners They Might Be Giants will also take place among the nearly-week-long slate of festivities during the consumer hobby, fantasy, science fiction and adventure gaming gathering. Gen Con has been hosted in Indianapolis for the last 15 years since its acquisition by Peter Adkison, the founder and former chief executive officer of Wizards of the Coast.

Gen Con LLC Chief Executive Officer Adrian Swartout says "our team is ecstatic to see so many choose to celebrate gaming history with us at the historic Gen Con 50. In this milestone year, we have seen gamers from around the world decide to make Gen Con their summer destination, and we're anticipating our best show yet. We've made optimizing the attendee experience a core goal for Gen Con 50, and we are committed to balancing growth with world class programming."

Organizers say last year's event attracted visitors from all 50 states and more than 60 countries.
