A multi-genre RPG focused on worldbuilding and storytelling.



Other Worlds is a roleplaying game of heroic action and adventure for any genre. The game is driven by description: descriptions of characters, details of actions, and dramatic visualisations. Numbers and dice rolls are secondary to the action; in fact, you will find that in Other Worlds the rules serve to emphasise the story and increase the drama rather than getting in their way. This book contains the following material:

  • A comprehensive worldbuilding procedure that the whole group gets to take part in
  • Over 100 ready-to-use character templates, from assassins to xenoarchaeologists and everything else in between
  • Detailed guidelines on creating your own cultural archetypes, professions, trademark powers, supporting characters, and adventure locations
  • A simple, elegant conflict resolution procedure that can handle any situation
  • Turn-based set piece rules to handle the more important conflicts of your story
  • A wealth of practical advice on how to get the most out of play, based on real experience at the games table
  • Quick-start genre packages for fantasy, horror, pirates, science fiction, superheroes, and the wild west
Available now from DriveThruRPG in any of three formats: PDF, softcover, or luxurious hardcover!

Discount codes sent out

Hi, I have now sent out $14.99 discount codes by email to everyone who bought the Superluminary PDF, so that you can update to a softcover or hardcover without having to re-buy the PDF. To get the discount you need to be logged in to your DTRPG account and THEN click on the link in the email. If you didn’t get an email, it’s either because it’s been filtered into your spam folder or it’s because you have told DTRPG not to email you at all. In either case just contact me and I will send the code to you directly. Please let me know if there are any problems. Thanks, Mark.

Red alert! Red alert!

Our sensors have picked up an immense energy spike from the Pericles Rift. Something is coming through. Whatever it is it’s big, it’s alien, and it’s on an attack vector coming straight for us. May the lord have mercy on our souls. Fire up the main batteries! All energy to the shields! Man the lifeboats!


This is not a drill. I repeat, this is not a drill.



Operative Training

Hi, am not dead, apologies for the radio silence! I have been thinking a lot about Other Worlds recently and when I re-watched The Bourne Identity I felt inspired to create a Treadstone-style trademark template. So here it is, an espionage/assassin type based around situational awareness rather than brute force.


Sanctioned Operative Training


General Abilities:       Identify Escape Route

Improvise Weapon

Infiltrate Compound

Lightning Reflexes


Photographic Memory

Sense Opportunity

Target Weak Point


Personality Traits:     Compartmentalise Feelings

Hyper Focused

I Don’t Make Mistakes



Relationships             [to civilian helper]

[to contact]

[to handler]

[to target]



Flaw:                          No Memory of Previous Life


So what do you think? Has anyone tried to run an espionage/technothriller Other Worlds campaign yet?

Upgrade Your Copy!

If anyone has the PDF and wants to upgrade to a hardcopy, let me know your OBS user ID and whether you want the hardcover or the softcover, and I will set you up with a $14.99 discount.
If anyone has a book but not a PDF, because you bought it in a shop or on ebay or whatever, let me know your details and where you bought it and I will send you the PDF free.

STARFIGHTER is coming…

Hey so remember that vapourware space opera supplement I was working on once upon a time called Starfighter? Well, I just got the manuscript back from the editor. Kickstarter, art, and layout are next on the list. Start watching the skies!
