As for licensing... erm I dunno, this is just my fan written stuff use it if you want please don't make money off it and get GW angry with me.
*chuckles* It's nothing to do with GW getting angry with you - don't worry. The reason I ask is simple - Gorkamorka is now over 15 years old. It'll be just as good a game in ten years.
Now think about copyright - if you wrote the rules you own them (assuming they're original work). Unless otherwise stated no one is legally allowed to share the rules without your explicit permission. They can't be republished, modified, built on, used in other things, or anything like that.
At tUGS we release rules under a Creative Commons Attribution-Non-Commercial-Share-Alike license (here's an example
). What this means is that if the rules aren't quite right in your opinion you can modify them and then release them, as long as you don't sell them and as long as you give credit to the author/s for creating the original rules. You can also use them in building something bigger - like a whole campaign book.
There's loads of old Gorkamorka stuff from the late 90s that can't be republished because the authors credited themselves as something like "Jim" and gave no email address. As a result they can't be shared with the rest of the world in any convenient and modern form (they're what's known as "orphan works
So how do you license something, it sounds like a lot of hassle...
It's actually dead easy. Head over here
, fill in the form, bam, done.
