After all those years playing video games, have you ever had ideas for one of your own? Now's your chance to put them to paper! We want you to design a game (video or tabletop), but here's the catch - your whole design document has to fit on one side of A4. This is, low key, A Thing among game devs; this GDC 2010 presentation explains the benefits of one-page GDDs as an exercise to force concise and holistic designs, and has a few examples to help inspire you. Feel free to use pictures and amusingly condensed fonts to cram more info into the space, but you must keep it to just one side.

Please write your documents in any online document format that you can share with a URL (Google Docs, for instance), and share that URL in your submission, along with any further commentary or context we'll need to understand your goals.
