Open Jam, an 80-hour game development event organized by @Jared-Sprague, @mwcz, and opensource.com, returns for its second year, inviting participants to create games within certain constraints, such as limited time, themes, or specific technologies, while encouraging the use of open source game engines, libraries, and Creative Commons assets. The event serves as an opportunity for both seasoned developers and newcomers to experiment with game creation, with last year's theme "Leave a mark" inspiring a variety of creative games like Stellar Wrath, developed with Godot. The top three games from Open Jam will be showcased at the All Things Open conference in Raleigh, NC, and participants can find theme announcements, tutorials, and details on the itch.io jam page starting October 5, 2018. Those unable to participate in Open Jam can look forward to GitHub's Game Off, a month-long game jam occurring the following month.
