OK, so Eberron was apparently a bad example. Let's try another - SCAG. Ignoring the clear disappointment folks had with the amount of detail in the book, it's neither a reboot like Ravenloft or Spelljammer, nor a copy-paste from 2E or 3E etc. with only updated mechanics. Instead, it makes some mild retcons, and largely just advances and continues the previous lore (even incorporating 4E). Like Eberron, this struck me as the winning move for mass appeal (unless you were a hardcore fan of the 4E Realms). But was that a bad call, to some of you veteran fans? Do you really think it would have been better as just a book of updated mechanics and lore copied from, say, the 3.0 Realms book?
