The Global Game Jam is a worldwide game jam, that has been running since 2009. For the 2020 Global Game Jam, 48,700 jammers attended 934 jam sites in 118 countries. Over 9000 games were made, all licensed under the CC Non Commercial Share Alike 4.0 free license. This talk will focus on the sharing, open spirit and impact of the Global Game Jam, as well as talk about some of the current challenges we have with the CC license, because copyright law sees them as complete creations, yet they are hybrid creations made of code, images and sound.
