📘 PDF Update & What's Next

Hey everyone, 

We wanted to share a quick update on where things stand.

The final PDF files are currently in the last stages of preparation. We're adding bookmarks, making final adjustments, and incorporating the feedback we've received from backers.

Thank you to everyone who took the time to submit errors and suggestions!

We will have the updated PDFs available this month.

🗺️ Label-Free Maps Included
One request we heard repeatedly was for versions of the regional maps without room labels.
We're happy to report that unlabeled versions of the maps will also be included.

Keep an eye out for our next update very soon! Thanks again for all of your support.

Production Update - Progress Across the Board
4 months ago – Fri, Feb 27, 2026 at 10:40:18 AM

Hey everyone!
We wanted to share a quick progress update because a lot is happening behind the scenes - and it’s the good kind of happening.

First up - Things are being made!

Collector’s Wooden Mimic Chest

Lots of progress on the Mimic Box. This was always meant to be something worthy of holding the World’s Largest Dungeon, and we’re really happy with how it’s turning out.

🗿 Miniatures
 

A little sneak peek of our Boss Monster Minis.

The packaging is looking super slick, too!

📘 Coming Soon
  • Secret Doors PDF is nearly ready
  • Mini STLs are also close to release
Both are in final preparation and will be distributed shortly.

🖨️ Books Moving to Print
The World’s Largest Dungeon books are going to print!
We’re accepting final error reports through Sunday. After that, the print files will be locked. If you’ve found anything that needs correction, please submit it before then so we can include it in the final files.

We appreciate the continued support. It’s good to see physical pieces coming together, and we’ll keep sharing progress as we move forward. 

World's Largest Dungeon - Final Feedback & Discord Shutdown
5 months ago – Wed, Jan 28, 2026 at 02:30:32 PM

Hey Delvers,

We have compiled a final list of errors to be resolved. That can be found here.

If you have anything else to add to the list, please email [email protected], and we'll ensure it gets added to the list.

We'll still update the digital files as they become available. So keep an eye out for emails from DTRPG.

That said, we are making a change to our support methods:

The World's Largest RPG Discord is shutting down.

Why? Quite simply so that we can serve you better from a more centralized location. The Discord was originally created by the marketing team behind The World’s Largest Dungeon, and while it helped foster early conversation, it has become difficult to track issues, requests, and support needs across multiple channels. Furthermore, the team behind the World's Largest Dungeon does not use Discord much, so having the marketing team serve as the go-between there was causing communication lag. 

Moving forward, all support, error reporting, and questions should be directed to [email protected]

This allows us to properly log issues, respond faster, and ensure nothing gets missed or buried in chat history.

We truly appreciate those of you who joined the Discord, shared feedback, and helped improve the project. Your input has directly shaped the final version of the game, and we are grateful for the time and care you put into helping us get it right.

Thank you again for your patience and support as we bring this project fully across the finish line.

The World’s Largest RPG Team
