In 2007, T-shirts for 2007 were hunter green and featured the MomoCon mascot; the staff theme was "The Family". The video game tournaments were reworked to feature a few large tournaments, as opposed to many smaller tournaments, and a larger costume contest was held at Georgia Tech's Kessler Campanile. The new costume contest location provided seating for a greater number of attendees, and was held earlier in the evening. Local area groups stepped forward to run workshops and seminars on their respective expertise, including a plethora of costuming panels and workshops, Japanese ceremonial demonstrations and game demos. On Sunday (March 18, 2007), the convention was closed nine hours early because several con attendees attempted to set off firecrackers inside the Georgia Tech Student Center.
