The 9th Edition has a great deal in common with prior editions of the handbooks that Hillcourt had helped write.
Later this year, all prior editions beginning with spring 1983 will be made available on this site.
However, all prior editions were written entirely by Guyton, with the eighth edition published in 1991.
Gingrich died in 1993, leaving Danker to complete the 3rd English edition based on all the prior editions and substantial work of his own.
The information in this article focuses primarily on the third edition (as the prior editions have significant gameplay differences).
This edition did not feature as many major changes as prior editions, and was "backwards compatible" with each army's third-edition codex.
The second change was the addition of a new game piece called the "spite token" (a variant in the prior edition).
(This change was approved in a prior edition of the code.)
It thus outdoes the prior editions, which had one-to-two page coverage for each episode.
Often enough, new editions are foisted upon students that provide little to no advantage over prior editions.
