Phil, Joe, Wulf, Ralts, et al:
Aside from game mechanics that are SRD derivative content (feats, classes, etc) that are regularly open, what else have you released as OGC that other publishers have actually used?
Hmmm... Quite a bit of stuff from
Heroes of High Favor: Dwarves has made it into use here and there. Usually with smaller publishers, but Mongoose used a couple of bits from Dwarves and Half-Orcs in (IIRC) Ultimate Games Designer's Compendium.
Corey Reid wrote to me shortly after Grim Tales came out and asked me if I would be interested in publishing his expansion rules that he had developed based on the Vehicles chapter in GT. His work was great, but quite a large expansion. I was rather enamored of the streamlined rules already in Grim Tales so I encouraged him to shop them to other publishers. Adamant Entertainment subsequently published
Hot Pursuit and I believe it was one of their best sellers.
Ralts already mentioned using the
Horror rules from Grim Tales in his own product (though I confess I don't even remember him asking).
My typical response, when someone asks me if they can use my OGC, is, "Of course you can use it, you don't even have to ask. It's Open. Just make sure you follow the license correctly and get my copyright notice correct in the Section 15. I do appreciate you asking, though."
A certain code monkey recently asked me if he could create an online character generator for Grim Tales characters. I released to him all of the electronic files he needs to do it, on the condition that when he is finished, he also post those files online into a "GT Character Creation SRD."
Grim Tales, of course, uses tons of Open Content from other sources, most notably Spycraft and d20 Modern, but there are many others (Joe already mentioned his "Economic Models" OGC which I used).
Phil Reed put out an inspired little PDF quite a while back called "Possessors: Children of the Outer Gods." The seeds of the idea he presented there fueled a good deal of Bad Axe's
Slavelords of Cydonia.
I assume there is a great deal more that I don't even know about. These are all top of mind as most of these folks have posted to this thread.
