Well it has been on sale a couple of times at least, like now, which is why I finally bought it ... cheap enough.
What I am confused about though, is the soundtrack, and the game page url, which mentions season pass.
Seemingly you could take it that the soundtrack is included, as there certainly is some kind of soundtrack included, but the separate listed soundtrack requires the Final Cut version, so I ain't sure what that means.
There is some mention of extra music, so maybe they are talking two different soundtracks?
Adding the soundtrack to the cart, doesn't show any warning either, so I am guessing it isn't included.
Anyway, at the current price for the soundtrack, I certainly ain't gonna buy it or take any risk.
This sort of crap happens a lot at GOG and maybe elsewhere ... lack of clarity with no excuse.
