Legends & Lore is Deities & Demigods with a new title.

I know what you are thinking: “Why change the whole title of this book if they weren’t willing to put the apostrophe in Dungeon Masters Guide?”

Answer: Controversy avoidance. Despite the upswing in sales from the various rumors and bad media swirling around Dungeons & Dragons, TSR wasn’t willing to court controversy. At least not by having the word “God” on the cover a book.

I vastly prefer the original cover but your mileage may vary.
