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 430+ page 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 Blackmoor, Edgar Rice Burroughs’ Barsoom and Pellucidar, Gary Gygax’s Flanaess, 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 30 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!

(A complete reference work designed to supplement existing pen-and-paper Fantasy Role-Playing Games.  4 parts, over 100 section topics, 71,300 words, over 350 pages; organized via a fully hyperlinked table of contents.  Just one of the proud creations available now from Wonderland Imprints — Only the Finest Works of Fantasy.)

I have the option of buying a physical copy of this book, is the formatting okay in a physical copy? Also is this more a Richard Baker's World Builders Guidebook, or more of a AEG's Ultimate Toolbox random table collection?

The preview looks so different from the kindle version on Amazon, this one is missing pictures and has an strange formatting. Is the kindle version better or the content is the same?

AWESOME BOOK! You know what you ought to do? Do the same treatment in your book series with a sci-fi/modern theme, encapsulating the range of genres.

Mr Kelly,
First, I am loving your book. I am even blogging my way through it as I build my campaign world. However, I do have a question about it. You reference ELD1, ELD2, and ELD3 about Saga of the Elder City. I am having a difficult time tracking these down. Are these books still available? If so, where would I find them?

Hi there Brian, good to hear from you :) I'm glad you're enjoying the book so far. Concerning the city state books, I've been taking down my DMsGuild 5E books, improving them, and re-releasing them on DriveThruRPG. 99%+ of my sales (literally) are on DriveThru and RPGNow, and <1% are on DMsGuild, so I routinely unpublish my 5E books and redo the material in the Castle Oldskull format. As of right now, ELD1 is available as CSE1, City State Encounters. ELD2, ELD3, and ELD4 (still in draft form) are being reassembled to create a more ambitious City State Design Guide. It's not done yet, but I will send out a notice when it's complete. I can say that you have pieces of ELD2 and ELD3 from owning Game World Generator already. ;)

I was wondering the same question after reading through City State Encounters. I'll probably be interested in the City State Design Guide whenever you finish it.

The file names are not very useful, and don’t even contain;the name of the book when truncated. May I suggest a different na,e convention that includes the book code and then the actual book title? It’s definitely getting lost in the “drive thru rpg edit” naming style.

I've downloaded this product and Adobe Acrobat does not like the file. Embedded fonts don't display correctly, large number of pages are blank, and Acrobat pulls up a warning every time I open the PDF. I'm on a standard Windows 10 machine using the latest version of Acrobat. I'm hoping this is a temporary glitch and the file is updated, because if it isn't, I just wasted five bucks. Not the end of the world, but I was hoping to actually read this document.

Hi there Keith, good to hear from you and thank you for the report :) I'm sorry that you're having technical difficulties with the file. I'm back home from the office now and can take a closer look. I've tried buying this PDF as a customer as a test, using three different PCs to access my account, and I'm having trouble replicating the error you're experiencing. But I can think of a few things off of the top of my head to see if the issue can be narrowed down ... [1] The download might be corrupted. Check to see if it's 10.3 MB in size, and re-download it from the purchase site. That should cost nothing and should allow you to replace the existing file. (You can rename the current file to V1 or whatever.) If the file was corrupted, a re-download should work out fine. [2] Try opening the PDF with a program that is not Acrobat. To do this, you can usually right click on the file name or icon, select Open With, and then go to something like Internet Explorer / Edge, Google Chrome, Firefox or FoxIt (a free...See more

First of all, thanks for getting back to me! The older version gave me the following error, "Cannot extract the embedded font 'ABCDEE+CenturyGothic'. Some characters may not display or print correctly." Without the font, old PDF displayed incorrectly, to the point of having blank pages. I had downloaded it a couple times, but had the same error each time. That said, the new version you recently uploaded works perfectly fine. It opened up without any issues and completely solved my problems. Thanks again. I appreciate the help!

Hi Keith, sure thing, you're welcome. Thank you for the detailed report on the error - it's a Microsoft-available font, but it's good to know that it might cause issues on some systems. I'm glad the current file is working well. I'm adding a bunch of chapters and additional features to the supplement this week, so there may be a new version soon. :) Let me know if anything else looks strange, it's very helpful to hear! - Kent

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.
