I would love it if you could include the soundtrack of Gothic 3 as a bonus in the extras. You already have them for Gothic 1 and 2.

As it is, the game is only accompanied by a couple of artworks and avatars.

Unless, of course, it's not possible due to copyright issues or publisher restrictions, in which case I'll resign to that fact.

I think that the problem is the official soundtrack cd, which was in the Collector Edition and generally can be found and bought quite easily.
However, you can extract the musics from the game in a very simple way: take G3Pak from this page and, when you open the .exe, search for the right archive .pak in Gothic 3/Data folder. :)

Another vote for making the Gothic 3 OST available as part of the goodies.

Aye, it really should be here.

If GoG fails us however. You can get it off YouTube from http://www.youtube.com/user/kubicq94 for instance with YouTube Downloader as well.

It's not the same.

It should be here on GOG to make things clean and easy.

The OSTs are basically the best goodies a game can have.

Absolutely, and I think GOG is well aware (but should be reminded) that soundtracks can really help a sale. (http://www.gog.com/wishlist/site/more_soundtracks_1 has over 1500 votes on the wishlist.) HOWEVER, please keep in mind that GOG has to license the music to sell it apart from the game; it can't just drag and drop the music files.

In the case of Gothic 3, given the professionalism of its soundtrack (presumably comparable to a movie score), the inclusion of it would probably raise the price significantly.
