About Global Game Jam:

The Global Game Jam® (GGJ) is the world's largest game creation event taking place around the globe, typically at physical locations. A "game jam" is essentially a hackathon focused on game development. It is the growth of an idea that in today’s heavily connected world, we could come together, be creative, share experiences and express ourselves in a multitude of ways using video games – it is very universal. The GGJ encourages people with all kinds of backgrounds to participate and contribute to this global spread of game development and creativity. 

The Global Game Jam is operated by Global Game Jam, Inc., an international non-profit corporation founded in San Luis Obispo, California, USA. Global Game Jam is run by a combination of hired staff, volunteer board members, and a small international team of volunteers.

About Core:

Core is a new, free platform for creating and playing games. With an endless universe of games to play and worlds to explore designed by a global community of creators; it’s a radically accessible game construction kit and game-playing platform, all in one. 

Core makes prototyping and iteration fast, so it’s a great platform for game jams, especially if you want to quickly set up a 3D multiplayer experience. You can get started making games right away using thousands of free, high quality music, sound, and art assets, with no coding required. Simply put, it’s a great tool for a game jam! 

Core is backed by the power of the Unreal engine, and it lets you create and customize your game as you see fit, from custom game logic in Lua to primitives and models that you can kitbash together with visual effects to create an elegant scene

Core FAQ:

Is Core kitbashing or making new assets?

- Both! New assets are created within Core by combining a wide selection of complex and simple shapes, hindered only by your own imagination. Our art director's blog post describes the ideology behind it all, for those who are curious.
