Here is another way to look at this (or beat this into the ground if you prefer):

Consider that any Atlas Age volume is a rare thing and one must pick and choose what gets done wisely.

With that in mind - is dedicating three (or even two) precious Atlas volumes to World of Fantasy a worthy use of resources? Would WOF 1-14 be more desirable than getting started on some more pre-code material (Marvel Tales, Battle, etc)? Is WOF even better than the other post-code World of Whatevers?

If the answer is no, then I say give us the Kirby\Ditko WOF with Strange Worlds in a single volume and let our children or grandchildren worry about WOF 1-14.

BTW - Other than what is in Masterworks, I have never read any of this Atlas horror\suspense stuff. I also have little personal interest in the material compared to the other genres. But I do love a good planning session with the rest of you!
