Ludum Dare, Game Jams and Licenses

Olofson's LD22 game

Free, open source licenses are underrepresented at game jams and contests.

This weekend's Ludum Dare ends in a few hours and it already counts 754 entries. The following authors mentioned open source licenses in the context of the compo/jam:

• roschdal plans on "releasing the game as open source on Github"
• Riley Adams's project is already there (GPL3)
• Agon's code is as well ("LICENSE: TODO")
• mcc released LD code as open source before, maybe it'll happen again?
• Olofson's (of Kobo Deluxe fame) failed submission is available (under LGPL)
• Furyhunter submitted a jME game (Not sure but seems to be GPL)
• kragniz's GPL game requires pyglet and pymunk
• lorancou made a HTML/Canvas game called lonekitty (GPL)

Here are some non-submission projects discovered on Ludum Dare:

• dwrensha released a SDL framework (GPL)
• KhaoTom mentioned the Spacescape skybox generator

A *lot* of other submissions use GitHub but have no license info. :(

I found above projects using this advanced Google search. Hopefully, there will be more results in a few hours, which would mean another blog post.

Here's a quick list of ideas how free licenses could get more attention in such events.

• Organizers could recommend free code and asset licenses
• Developers could offer porting non-cross-platform submissions in exchange for release under free licenses
• Participating developers, who already use free licenses, could advertise these in blog posts and announcements (more)

The Global Game Jam for example requires use of the CC-BY-NC-SA license, which unfortunately is non-free though.

Let us know of any freely licensed game jam/competition entries which we didn't cover!
