If its that infrequent then surely such a table wouldn't be such a big task.
Feel free to set your parameters as widely as you wish; I can only say what I feel.
I would have thought that of the 15 or so editions for any given adventure only 2 or 3 of these would not be a complete mirror of the previous edition.
Again, if that is the assumption you want to make, then that's your choice.
However, the survey wouldn't be definitive or complete, and you yourself have been searching for absolutist and definitive answers about specifically which
books/ editions have changes, what specific editions facsimiles are of etc., and expecting that information to be available.
My point has been that until you or someone has carried out the researches into everything
, then the specific answers you have been looking for can never be as absolute as you appear to want them to be.
So in your opinion is The Black Island the only book with significant changes from the original color version?
No, I didn't say anything like that; it was specifically an example
in reference to your point about cars being changed.
You seemed to think vehicular modification was a major aspect of the changes in the books; I am not aware of it being done on an ad hoc
basis - but in a book like The Black Island
, where everything was re-drawn, they would have been. But it wasn't the sole purpose or intention of the re-drawn version, and in other books with wholesale changes to artwork including Cigars of the Pharaoh
, Blue Lotus
and Land of Black Gold
, cars and vehicle may have changed too.
I was trying to get across that I know of no book in which vehicles were specifically altered, but the rest of the frame remained untouched.
There really is a lot of information available about how books have changed in these forums - perhaps doing some searches and reading on those topics will give you a better idea of the sort of changes which have happened?
