Every now and then someone inquires as to the prospect of writing material for my games and supplements. Since it’s a question that crops up regularly, it seems worthwhile to put things down here where all the interested parties can see them. While I can’t represent the following as a properly particular legal contract, I can say that if you stay within these lines I won’t object a bit to whatever you might care to do.
First, all non-commercial writing of any kind is welcome. Feel free to reference my settings or reproduce any of my free material. If you’re not charging money for it, you should feel free to do what you like.
Second, whether commercial or non-commercial, you should feel free to copy any and all of the mechanical elements of my games provided you use your own wording and setting content. If some questionably-rational soul wanted to clone Stars Without Number and redid the entire book in his own words and with his own setting, well, I’d applaud his dedication. If you like concepts or ideas in the book, feel free to reproduce them in your own idiom. If you think the end result is reasonably compatible with Stars Without Number or one of my other games, you can feel free to plainly say as much as well, provided you don’t represent the work as being “official” content.
Third, if you have some project that doesn’t fit the above, you can always ask me. Not everything fits my plans for my game lines, but it can’t hurt to ask.
Hopefully the points above will be of some use to designers who want to do something with the games and supplements I’ve written. I welcome any interest in my games, and it’s always a pleasure to see people getting some profitable use out of them.
