So if you're new to game jams you might not have heard of Ludum Dare. It's the largest game jam that happens 3 types per year. Each Ludum Dare starts with a keynote video to help new-comers understand what to expect and tips for making the Jam fun and successful. Below is my favorite keynote from LD35, even though it was made for Ludum Dare everything in the video applies to any game jam. So it's worth taking a look especially if this is your first Jam.
