- The BFRPG book where they first appeared
- By whom and when they were created (origin)
- Any references to "prior art"
- A suggested substitute monster in use in the most recent version of BFRPG
The origin of many monsters are part of history, science, and folklore. Others were imagined by novelists and game designers.
When possible, links to prior art are provided. Most invented monsters can be traced to references old texts. Some are understood to have appeared in games books from the 20th Century. This information may be interesting with regard to copyright and the free use of such information.
I will process posts to this topic into the spreadsheet. If it fills out, we can turn the information into something more like a reference text with more commentary. I hope it will be useful for anyone working on game rules.
