What is different in the Limited Edition version of Myst V: End of Ages?
Solution 1:
I have not bought the game on GOG.com, but as far as I can tell, the original limited edition includes additional bonuses. Wikipedia says the following:
The limited edition contained the original soundtrack, a collector's lithograph, strategy guide, and a bonus DVD with a "making of" retrospective on the Myst franchise.
On Amazon:
Special Limited Edition contains: Bonus DVD with soundtrack, trailer and making-of documentary; Exclusive 152-page collector booklet with world-premiere preview of the new Myst book, The Book of Marrim.
The GOG.com version has the soundtrack and documentary as goodies. The physical items are of course missing. According to the store page there are no digital versions of the strategy guide (unless it is part of the manual) or preview of The Book of Marrim.
