Man, this is gonna vary so wildly depending on who you ask and what kind of 'variety' we're even talking about. Is it a special anniversary thing, a boxed set, or like a 'collector's edition' with extra fluff? For me, the absolute non-negotiable is new material. I'm talking deleted scenes, author commentary tucked into the margins, maybe an alternate ending or some early draft chapters. If it's just the same book with a fancy cover and a ribbon bookmark, I feel a bit cheated.
I've got this leatherbound of 'The Name of the Wind' that's gorgeous, but it's the author's afterword about the ten-year journey that makes it shelf-worthy. The physical stuff matters too, though—quality paper that doesn't feel like newspaper, sewn binding that actually lies flat, illustrations that add to the world and aren't just generic filler art. And maybe this is petty, but if the new cover art clashes tonally with the book? Hard pass. Saw a 'special edition' of a grimdark fantasy with a cartoonish, almost anime-style cover once. Who approved that?
Ultimately, a true variety edition should offer a different experience, not just a different object. It's for re-reads, for deeper dives. If I wanted just the story, I'd grab my battered paperback. The key features gotta justify why I'm reaching for this heavier, more expensive version instead.
