G²C² is an annual gaming convention. The focus of G²C² is on alternative or ‘face-to-face’ gaming. They have a cosplay competition, tradable card games, role-playing modules, and miniature wargaming. Upcon (G²C²) is also known for its variety of stalls. Although the con itself does not focus on electronic gaming, most attendees also play electronic games.
Events at G²C² are both hosted by the G²C² organisers and by members of the public.
