I'm used to doing smaller game jams (48 hour / 72 hour). For anyone like me who doesn't often participate in long-form game jams, please learn from my mistakes in Game Off 2017 and don't leave all of the work until after Thanksgiving. Get an idea, figure out what your scope should look like, and set intermediate goals for yourself! Our team basically ended up with a game that could have been created over a weekend, even though we had a full month to create it. If we had kept a consistent schedule and set some checkpoints, we could have made something a lot more fun and interesting. It's hard to keep motivated over the course of a month, but having some goals to hit throughout the month will probably help you.
