I got them all with the exception of the mags and Vicki. I posted a series on my blog about them and wanted to see how the stories turned out/ how the third issue switch affected the titles I hadn't completed so I filled in the issues I was missing.. Planet of Vampires might have started of to ape Omega Man/I am Legend but by the time the third issue switch rolled around you have a planet with vampire spiders/vampire people/ and who knows what other kind of vampire creatures they had planed. I think it went pretty far from the source by the time it ended with issue 3. My personal favorites are Targitt (before the switch/new direction really hit with issue 3), Brute (Michael Fleisher written issues) Steve Ditko's work on Destructor, and Morlock 2001. Grim Ghost was a good title plenty of potential and Phoenix was one of the few Atlas titles that the third issue switch/new direction actually made even more interesting. Atlas/Seaboard stood out to me because it pushed the limit of what you could do in comics father than either Marvel or DC did back then, I don't know if the new relaunch will carry on in the same vein but I'm looking forward to giving it a shot.
