Dave Thompson (of Guile Chickadee, The Spritely Institute, and - tips hat - Guile Hoot fame) has announced the 2024 Autumn Lisp Game Jam over at itch_io:
In the opinion of this Racketeer wannabe, the Lisp Game Jam is a great annual event and a good showcase of the Lisp (extended) family of languages in action; and there's usually some good games written in Racket in there.
(N. B.: Posting this under "General", since I see the "Announcements" category is for Racket release news. Do correct me if this is the wrong category, though.)
