Heroic Sci-fi Roleplaying for 5E

First announced in August 2016, EG was refined through several playtests in order to introduce fast and fun sci-fi gameplay while staying completely true to the 5E core mechanics. If you know how to play D&D, you already know how to play EG.

These free Basic Rules provide everything you need to begin an Esper Genesis campaign for character levels 1-10. Five more iconic races and four additional classes are provided in the full version of the game - beginning with the Esper Genesis Core Manual.

This is a standalone product. You do not need the D&D rulebooks or any other 5E product in order to play. This product contains:

  • Five playable character races from the Silrayne Arc
  • Four core 5E Character Classes: The Engineer, the Melder, the Specialist, and the Warrior
  • Sci-fi tailored backgrounds, equipment, and gear to round out your galactic pioneer
  • Esper Talents and Techniques, the power to warp time, space, and matter
  • Starter rules and options for vehicles, space travel, zero-gravity, and starship combat
  • A brief overview of the Crucibles and the Silrayne Arc
Looking for threats and game tools to use for running your own Esper Genesis game? The included Game Master's supplement provides you with the basics needed to challenge your players in the Esper Genesis RPG. This product contains:
  • An introductory set of sci-fi threats
  • Rules for using Enhanced Items
  • Starter tables for random star system generation

Since they're focused on the physical, shouldn't their Ability Score Increase be something physical like Strength instead of the listed Wisdom, which is the same ability score increase that the Cerebral gets

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.
