I don't get this need for a DMG. Everything you need to know to run the game is in the PH, except for a way to handle magic and treasure, and that is in the M&T.
So I don't see what is missing that the DMG type book is supposed to fill. Advice on how to run the game? They give exmaploes of how to use the rules, in the second printing. Now if your talking from your experiences in the first printing, then your right.
In the second printing they give a example situation for how to implement the rules for every "type" of roll, such as saves, class abilities, non class actions, hitting, etc...
The first printing is missing all of that.
What I am looking for in the CKG is guidelines on how to implement rules from the other editions of D&D, Basic up to 3E. How to design classes and determine their xp progression based on their class abilities, etc... How to implement feats, how to use a spell point system, etc....
Nothing I need, because I have already figured out how to do almost everything I want to do. I just want the rules for building classes. Reverse engineering monsters is pretty obvious to me in the M&T.
I agree the Dragons are very tough, and I am glad of it. 6 HD Ancient White Dragons like they had in 1E was pathetic.
I also agree C&C as written wasn't perfect for me, but with a couple of house rules, and tweaking a couple of the classes a little bit, and being able to use monsters and modules from every version of D&D (and OSRIC), its the best game for me.
As for the Goodman C&C DCC's, The Mysterious Tower is basically retro fitting the 3E version to C&C, and it works pretty well. The other one, Palace of Shadows, or something named like that, was written specifically for C&C and my group liked it a lot.
Assault on Blacktooth Ridge made me think of Keep on the Borderlands so strongly that the next time I am going to blend them together. So I liked it. I didn't think I would like Slag Heap, but it played surprisingly well and my group really got into it, character wise.
Just shows how "mileage may very" is a very true statement.
