Here’s a writing contest, for any writers (or artists) looking to get into top RPG writing. Go to https://www.dungeoncontest.com/ and you’ll find information about the One Page Dungeon Contest.
The competition is for you to write and map a dungeon which is no more than a single page long.
Each adventure is designed to be system neutral, so that it could be used with any edition of Dungeons & Dragons, Pathfinder or another gaming system. Therefore you are told not to include stats, just provide some-kind of map, a key and some generic monsters that can be found in any of those games.
And honestly, even all that is open to interpretation. Entrants are encouraged to be imaginative in their approach.
Further details can be found on the submissions guideline page; https://www.dungeoncontest.com/submission-guide
The deadline is May 1st, 2019.
However, the competition does run annually if you don’t have time to enter this year.
The winning entries will be compiled in a book, available as a pdf and as print-on-demand.
Sponsors include Kobold Press, Green Ronin Publishing and many others.
