You've a good point about the music :
I experienced this :
in the time my KS box came I can't start playing D:OS because I hadn't have my new laptop yet,
so I listen many times to the soundtrack CD of Kirill and that were very beautiful moments !
The whole bunch of tracks sucks me into the world of Original Sin !!
Then after a while (I bought a new laptop) I play D:OS and listen to the music tracks whilst playing I was suddenly suprized :
* I was a little bit disappointed because of hearing tracks from earlier Divnity games ....
* because the D:OS sound tracks I hear on the CD of Kirill fitting much more the atmosphere of D:OS !
* "nostalgy with music/sounds" can be a strong element in a new game, but can also break the right atmosphere (for me this is a bigger issue than I thought at first!) !
Sorry to the Larian Team to say this. I really love the D:OS sound tracks so so very very much that I don't want to hear (too) many times in the game sound tracks from earlier games ....
It's because of this that I lowered the sound almost to ZERO ! That's really a shame, I know, but then the visuals I see are at laest all full of Original Sin atmosphere sucking my soul into the game

!!
Also thanks to the Turn Based Combat my inner push to replay older Divnity games is totally gone : see this as a big compliment for Divnity Original Sin (or: Eyes of a Child - nice cover and title!)!
It means that I love D:OS so much that my Soul came finally free from earlier Divnity games ! Or maybe here's something lurking at the corners of my thoughts

...
that can be ... no ... it IS ...
