Everything was very smooth and the quality of the product was better than expected! The print outs are already getting me excited, and honestly the portraits I plan to use in my existing campaign for some NPCs and then later in the booklet one.

The digital version is amazing. It has so much that I am adding to the prewritten campaign I'm running. It's bringing the world to life & my players are loving it.
I can't wait for the physical copy to arrive.

This is truly an epic city! Not going to lie, when I run games from here on out; this will be what I use for settlement layout/encounters (tweaked as needed).

The Gooey Difference

Immersive 5e Adventure Modules for Game Masters

Gooey Cube creates tabletop RPG adventures designed to help Game Masters run rich and immersive campaigns. Each adventure includes narrative storylines, encounter guides, full-color maps, handouts, and character portraits so you can spend less time preparing and more time running the game.

Our Philosophy

The Gooey Way

At Gooey Cube, we believe that immersion and story are the beating heart of every great game. And that belief shapes everything that we do... from the tales we tell, to the tools we build, to the worlds we invite you to explore.

It fuels our creativity. It colors our imagination. And it drives us to craft supplements and scenarios that help GMs, across all experience levels, weave unforgettable adventures of their own.

Our mission is simple: To help you craft tales that will wow and enthrall your players... stories they'll talk about for years to come.

Because nothing matters more to us GMs than hearing, "Wow! That was a great game."
