As a preparation for the jam I set up a personal jam from the 14th to the 18th, and found it wasn't so much fun as "Nice", until the deadline day as my plans were disrupted and the mood shifted more towards "Stressed, but Done"
I like the idea of making the process of game development fun and enjoyable throughout, but I can't really think of how to go about that.
What have you guys done to make it more fun for you?
