This document represents a compilation of rules for old school-style fantasy gaming. The book is intended to reproduce underlying rules used in the late 1970s to early 1980s, which being rules are not subject to copyright, without using any of the copyrighted “artistic presentation” originally used to convey those rules. In creating this new “artistic presentation,” we have made use of the System Reference Document produced by Wizards of the Coast (“WOTC”).
The reason for going back to square one and restating the underlying rules is simple. It allows old school publishers (both commercial and fans) to reference the rules set forth in this document without making reference to any protected trademark. (This document is trademarked, but the use of the trademark is permitted under the terms of the OSRIC Open License—see below). By using this document in tandem with the Open Game License (“OGL”) of WOTC, a publisher should be able to create products for old-school fantasy gaming and clearly refer to this particular rule set without violating the terms of the OGL.
Thus, in many ways, this entire book is nothing more than a tool for old-school writers, a stepping stone to put the original, non-copyrightable portion of the old-school rules into an open license, as permitted by law. Great pains have been taken to ensure that we have used none of the original artistic presentation, for we have the greatest possible respect for the authors who originally created these games.
We considered the non-copyrightable rules to be the numerical algorithms that would be in a computer version of the game (most precedent in the area of game copyrights has come from computer games, not RPGs), and have included these and the relations between the results of the formulae. “To hit” numbers are a clear example. On the other hand, level titles other than “name” level are clearly artistic presentation and are excluded.
When “name” level does not create a numerical effect such as taxes from a stronghold or the ability to improve fighting power with followers, we have not used name level titles, even though the titles themselves are generic words.
In a few cases you may find that rules themselves have been clarified, or are more based on the SRD than on original rules (when it was difficult to separate rules from artistic presentation). The greatest difference is in the inclusion of some random factors into the experience progression.
