Hello. :)

Pretty much what I described in the subject.

I remember that there was some sort of DLC for the game that had to do with a Labyrinth of sorts, and wonder if that and all such extra content come with this version.

That's it.

Thanks for any answers regarding this question.

Yes, it's "Game of the year" edition, so including all the DLC.

Thanks a lot for the response.

I guessed as much, but the game page here at GOG didn't specify it, so better to ask.
:D
