Not so, Decipher's books ALSO had to rename them.
Well, on a technicality. Wasn't Decipher essentially continuing the line that LUG already began, by publishing the manuals LUG already had in the production line, but couldn't complete, and now tweaked to mesh with the new Decipher games? Same previously-announced titles, same authors, including books already commissioned by LUG containing the same references to Rigellian felinoids (previously known as Caitians).
I'll adjust my original statement.
