What is the difference between the Collector's Edition and previous normal versions of Machinarium?

I had previously bought this title on Impulse when it was still run by Stardock and they were doing more indie titles. I too am wondering what the difference is?

Also get World of Goo on here. I lov it so muchI bought it from Impulse, and Windows live!

:D

I quote Wikipedia:

Machinarium Collector's Edition (United Kingdom) - includes dvd with game, soundtrack in digital format, cd with soundtrack, printed walkthrough, A3 poster and concept art.

I think GoG sells the Collector's Edition because gives all this stuff in digital form.

Ok thanks etb. I got the OST as part of the Game Music Bundle 2 and it is pretty great. I must have listened to it at least a dozen times.

I would like to underline I said ``I think''. I hope we get a more official answer from the gog team.

Beside I just noticed gog does not give a digital copy of printed walkthrough,

Can someone who has bought the Collector's Edition from gog.com confirm whether or not it contains a digital version of the walkthrough/hints book?

If it doesn't, most (if not, all- I think?) of it can be found on Amanita Design's forums:

I bought it and there is no digital walk-through or hint book.

It is a bit of a shame I have the DVD Collector's edition and it would be a nice little booklet to have in PDF form through GOG. Maybe the developers have a rights issue with the distributors for the DVD edition.

If the collector's edition has a printed walkthrough i think it should be included even in the GOG version as a pdf
