I think the mentioning of where Wound and Vitality points were first introduced is not really a violation of the OGL. If I were to use mechanics of the Star Wars RPG as examples, then I would be in violation. But to mention the origins of a particular game mechanic shouldn't be a problem.Anonymous wrote:The Star Wars Roleplaying Game is mentioned in the first line of the Wounds & Vitality article/section.
A clearer violation would be in the Sanity rules:
Metagame Analysis: Sanity
Because it affects the way that characters interact with the creatures and objects that they encounter on their adventures in many different and profound ways, this variant, perhaps more than any other in Unearthed Arcana, can alter the entire feel of a campaign. If you adopt this variant in your campaign, the largest change will most likely be one of tone (this applies to an even greater extent if you adopt the entire Cthulhu Mythos that the variant is based on).
As in the Call of Cthulhu Roleplaying Game, characters feel more vulnerable, for no matter how powerful they become, the dark gods are always greater. Religion is not only a source of comfort or succor, but also a dangerous enemy. (In those games that use the Cthulhu Mythos, religion seldom provides any succor at all.) Characters are suspicious, even paranoid, for a seemingly innocent commoner could secretly serve a cult. And yet, with such dark challenges come the opportunities for greater heroism.
