Well it's pretty obvious when you think about it, isn't it? I mean, beyond sales dropping like a stone, even apart from those sort of real life considerations.
Just some highly speculative musings.
Just trying to point out that there's only ONE Judge Dredd, or ever will be. Judges Fargo, Rico, Kraken... all have identical DNA, but they're all individuals with different life experiences, memories, and beliefs -- and all of them are capable of making different free-will choices. "Judge Dredd" isn't some mask or costume that can be handed down to a successor like a legacy. Judge Giant is Judge GIANT, not Judge Dredd. They already have similar roles in the sense that they have the same job description - they're both Judges. Dredd is Dredd, Giant is Giant, Anderson is Anderson. If Anderson can have her own series, so can another Judge, if deemed popular enough with the readership. None
of those characters will ever BE "Judge Dredd", though.
Besides, if they had to change the title of the Megazine to Judge Giant Megazine
, it might lead all sorts of confusion and misunderstandings. "I don't get it -- it's just a regular-size edition of the magazine, with no extra pages?!"
