CASTLE OLDSKULL - Game World Generator - Deluxe Edition


Please Note: This Deluxe and Revised Edition of the Platinum Best-Selling Game World Generator is actually two books in one.  It is a fully expanded, reformatted, re-illustrated, and re-edited version of the original Game World Generator, along with a new 70,000-word book -- my requested City State Design Guide -- which is featured as a part herein, where the previous edition ended with very little city state information.  The two books are united as a continuous narrative due to the number of requests made by GMs for these associated topics over the years.  This Deluxe Edition supersedes the existing Game World Generator (GWG1 V1), which remains available separately at an introductory price.  The original edition's 71,000 words have expanded with new material to encompass 161,000 total words in the Deluxe Edition, thereby featuring more than double the content, and making this volume now my most extensive gaming supplement to date.  Enjoy!


Affordable excellence. A Platinum Medal Best Seller (DriveThruRPG & RPGNow), now fully revised and expanded with more than twice the original material.


Wolf-haunted wastelands of frigid tundra,

Veiling lost cities sunken and frozen into the ice …

Mist-wreathed mountains teeming with orcs,

Goblins, demons and dwarven underworlds …

Burning battlefields, reigned over

By imperious and ancient dragons …

Steaming jungles, filled with headhunters

And savage apes, guardians to ancient temples

Filled with accursed gold …


These are the realms of old school fantasy role-playing, the world of your imagination. This world is a dark and wondrous place, an endless milieu teeming with danger, intrigue, exotic wonders, epic quests, and the bold heroes and villains who dare to conquer all. And you, as the Game Master, are tasked with creating those kingdoms from scratch. It is your mission to forge an entire alternate universe filled with infinite possibilities, a world which your friends and fellow role-players can explore for years to come. But how do you create a world? How do you even begin?

The CASTLE OLDSKULL GAME WORLD GENERATOR is the only guide specifically and solely designed to assist you in creating an entire old school fantasy world. This is no “It is time for you to take the world into your own hands, and no one but you can decide what to include” copout dodge which demands everything of you and gives you nothing. This is a massive step-by-step guide, from blank hex paper to the fully-realized game world, which explains the entire process to you in granular detail. Even better, this book is filled with dozens of helpful graphics which illustrate the entire mapping process. If you love lost worlds like Dave Arneson’s “Black Marsh,” Edgar Rice Burroughs’ Barsoom and Pellucidar, Gary Gygax’s “Gray Kingdom,” Robert E. Howard’s Cimmeria and Hyboria, Fritz Leiber’s Nehwon, H.P. Lovecraft’s Dreamlands, Michael Moorcock’s Melnibone and J.R.R. Tolkien’s Middle Earth, then this is the book for you!

Highlights include: world conception, mapping, scale, landforms, terrain, kingdoms and fiefs, wilderness design, feudal realms and foreign equivalents, city and wilderness names, treasures and resources, hierarchies of nobility, ruler classes and levels, realm alignment, campaign-tailored population formulae, demi-human enclaves, humanoid tribes, starting area development, dragon lair placement, dungeon placement and much more. Everything you need to turn your ideas into a solid, coherent and adventure-filled world is right here at your fingertips.

The GAME WORLD GENERATOR is brought to you by Kent David Kelly of Wonderland Imprints, a role-player and Game Master with over 35 years of play experience. Best of all, if there are any other materials you would like to see relating to world or dungeon design, feel free to contact the author. I create the supplements that Game Masters want. Many more CASTLE OLDSKULL supplements are being prepared specifically to support the players, initiates and Game Masters of the Old School Revival (OSR). This book is your gateway to the realms of sword and sorcery. Join us for the adventure!

I keep meaning to ask.. the system generates the number of ancient dragons. Is there another system for breaking down the number of younger dragons from the number of ancient dragons? Maybe in another book?

Hi there Brian, you could probably decide on survival rates for each of the 8 growth stages ... for example if you had the stages as 50% fatalities each, there would be 128 very young dragons, 64 young, 32 sub-adult, 16 young adult, 8 adult, 4 old, 2 very old, per 1 ancient dragon (approximately).

Hmm, just a miserable 5 bucks full price.
I've seen the original items, it was nice to get this as a combined item.
Nicely done text and modest illustrations.

This is something I'd buy in hardcover willingly.
Nice product Kent.

Hello Kent, how much of this book is new from the original Game World Generator and City State Encounters (since I've bought both already), I.e. is the City State Design all know from the CS Encounters? Will the new materials be offered as a standalone product?
Customer avatar
Kent K July 23, 2018 10:14 pm UTC
Hi there Pierre, good to hear from you. The world generation part of the book has some new material, but most of the new material is in the City State Design Guide (CSDG). It supplements the City State Encounters book, but does not duplicate it; it's more about city design than encounter design. The CSDG covers about 170 pages of the book, so it's about 40% of the book. If you like, when I get back from vacation I can make the CSDG as a separate volume. It's highly dependent on the Game World Generator but could be regarded as a "supplement to the supplement" or part two of world design.

Hi Kent, since there is new material in the GWG I likely just buy the new version so I can just keep one file for use.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
