The Global Game Jam (GGJ) is an annual event in which participants
design and create digital and non-digital games over the course of one
weekend. At each site, participants gather to develop ideas, form
small groups, create new, creative, innovative games, and present them
to their peers and the global community, all in a limited time span
(about 48 hours) . In January 2011, the event generated teams in 44
countries, who over the course of one weekend created over 1,500
games.
