Well, I'm the original creator of it, but I don't maintain it anymore. Still, with my name on it, I'd like ot think I'm not associated with any piracy issues. Just wanted to clear that up.
Myriador own the rights to the d20 versions of the Fighting Fantasy books. I know that Knights of Doom isn't, at this point, in the works.
Or did you mean a fan-based conversion?
We started at level 1 and got to 24 before 'retiring' the characters for the time being, mainly because we were running out of ways to challenge them. I look forward to the 30th level adventure.
