I've been meaning to ask: if I was to start working on some OSR-related homebrew with the intent of posting the results on a blog, am I allowed to re-use the concept and mechanics of the likes of Facts as used in the likes of Scarlet Heroes and Godbound? It's not any work I intend to sell for profit. It's just that your games have been a rather solid foundation for my current attempts at homebrew and I would like to know what can and cannot be re-used from them.
Mechanics can't be copyrighted, and even if they could be, an OSR author has no business getting miserly with mechanics. I'd consider a restating of Fact mechanics or Effort or such in the author's own words to be entirely legit for personal or commercial use.
Commercial use is not the intended goal or purpose right now, merely posting the material on my blog. Heck I might just simply flat out post the crunch as houserules for Scarlet Heroes, depending on it's intended final form. It's just I've generally worked off Scarlet Heroes, Godbound and Exemplars & Eidolon as a baseline for crunch much like how many bloggers tend to use a game as a baseline, usually Labyrinth Lord or LotFP. In my case it just happen I've worked off your games.
Which make me wonder: how much conversion work does it require to go from/to Scarlet Heroes, as what I'm currently working on could work both as a setting for solo adventures or more classical D&D-style larger groups and I'd like to note down two version.
