Well, I have to be honest. I would have been completely disinterested in an RQ version (or any other version of different rules) for Conan. Not because I have any loyalty to d20, but because I just finished buying the d20 books. I'm a late comer to the Conan RPG, but my gaming group and I have been having a blast with it. Most of my players (many are new to gaming as a whole) just learned the d20 system. I'm not about to suddenly stop and tell them everything has just changed.
As for the Atlas though.... wow. I'd have loved that. I absolutely love atlases for all sorts of worlds (even our real one) and I would bought that as fast as it hit the market. I'm truly saddened to see it go (if, in fact, it has).
I'm all for more d20 books, though, much like the Warrior's Companion, I'm not sure they will see much use. More adventures would be great because, frankly, working 2 jobs and this many hours kills the prep time for an RPG anymore.
If they print compelling adventures or background for Conan in any system, I'll snatch them up.
Just my 2 copper pieces.
