GDEX is the convention dedicated to a love of games and creative technology, located in Columbus, Ohio.  GDEX features a weekend expo showcase, combined with presentation sessions, artist alleys, raffles, tournaments, and Charity events. The GDEX expo is a curated showcase of some of the most exciting up and coming developers so that you can see the latest games before anyone else!

GDEX started in 2013 as a community event to bring together Ohio game developers to Connect with each other, Share their projects and technologies, and Learn from each other as well as industry professionals. It has since grown into the Premier event of its kind in the Midwest, drawing an audience from across the country with unrivaled quality in educational sessions and opportunities for individuals and small businesses to accelerate their growth. There truly is no other event like GDEX in the Midwest, and we are proud to be a part of making the community and industry in the area.
