THE BUILD is the December 2019 release of The APERTURE Guide, an ongoing series of games built atop our custom APERTURE system. By purchasing this product, you automatically get access to all past and forthcoming content from The APERTURE Guide at no further expense. 

We are also offering this as a Pay What You Want subscription for those suffering from financial hardship or other disadvantaged circumstances. Whether you pay with cash or enthusiasm, we're happy to have you. 

Within THE BUILD, Players will take on the task of building the most impressive dungeon in the world of Khylaeron, an original fantasy world created when a dying goddess fell onto the rocky planet's surface eons ago. The group must circumvent a dangerous culture and rival builders, use their magical and mechanical abilities to create a new wonder of the world (on budget), and flex their growing socio-political network to destroy adversaries.  


The APERTURE Guide is an anthology gaming series that leverages our D20-based Aperture System to take players on a vast array of adventures in different genres and settings.

Quickstart Rules are available within every release, making it easy to start with any Issue or Scenario and get up and running fast. In addition, many Issues come with an installment of The GUIDE'S Guide, an overview of Tips & Tricks to support those running the Aperture System or a specific Scenario.


The Aperture System is a custom resolution system for roleplaying titles that leverages one die and one die alone: The iconic D20. Though fashioned as a ‘generic’ system for use in any type of game, genre, or setting, Aperture was designed to be opinionated: It wants you to do awesome things in a ridiculous number of ways, as opposed to merely deciding ‘Yes’ or ‘No’. Its mechanics are intended to encourage creative thought, storytelling within a roll, and common sense collaboration across your party.

Though designed as a Skills-based system first and foremost, it provides straightforward guidelines for how to reproduce classes, playbooks, or other such templates within the system’s operations with ease. In addition, it’s flexible enough to tailor Skills to your group’s preferences. Light or heavy, you can set it just right.

Original electronic
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.
