I guess I dont really understand your comment about "different creative ideas and marketing ideas" vis a vis you and rob. What difference would rob's ideas on marketing have on this project? Hadnt the general form (dark chateau plus 10 or so books) been set for a long time? I am generally aware of his new "sponsored projects" initiative on his website. Was he trying to change the published form of Zagyg?
With respect to the different creative ideas part, Im a little surprised by that as well. Was there something in Dark Chateau that you disagreed with (I thought it was good). Comparing Dark Chateau to the other 20 things written by you that I own, there are certainly differences in your writing styles (most obviously: GG is the master of brevity with the Steading at 8 pages, Hommlet at 32 pages, etc.), but Im not quite sure I see that many giant creative differences. Rob is probably a bit more "ornate" in his encounters whereas you tend to leave a bit more to the DM, but that didnt seem like a giant discrepancy.
I'm not trying to arouse any animosity between the two of you (and Im not trying to say anything nasty about Rob other than express disappointment that my favorite project will be delayed again), I am just trying to understand what happened. I'm curious whether you think Dark Chateau is a viable entry point to the Castle Zagyg that you envision or whether you think it would be wise to start elsewhere.
