Following the success of last year’s Vaarn Summer Jam, I’m hosting a second annual game jam on! The submission period will run from the start of June until the end of August this year, making it a true summer event.

The returning Summer Jam is a non-ranked game jam, where entrants are invited to contribute submissions relating to Vaults of Vaarn, and science-fantasy roleplaying games in general. Entries can be adventures, maps, artefacts, NPCs, art packs, or anything else you can dream up. I have a very loose content policy but please don’t submit stuff that has no relation whatsoever to science-fantasy. I would like all entries to be conceptually compatible with Vaults of Vaarn, even if they’re not actually written for the setting or system. To see last year’s submissions click here.

All Vaults of Vaarn material presented in the original three zines and on the SRD is covered by a Creative Commons 4.0 Attribution license, and you are free to use it however you want in your submissions to this jam or other projects. The new artwork and adventure locations I produced for the Deluxe Edition are copyright to Games Omnivorous and can’t be reused. 

I will endeavour to feature all entries on this blog when it’s over. I look forward to reading what people come up with!

Come join us on the Vaarn discord server to discuss your work in progress.

  1. Hello
    I’d like to contribute an art pack to the game jam.
    Could you please provide image info such as file types, image size and resolution?


    1. There are no regulations, I think making something that people could use in print if they wanted to (300 dpi) would be appreciated. I usually go for PNG when sharing stuff.
