Best game soundtrack ever: Ys - The Oath in Felghana

Sadly neither the soundtrack nor the game are on gog.

From the list you have posted I can recommend the Realms of Arcania soundtracks.

I often listen to the soundtracks of these games. :)

-HoMM 2/3/4/5
Settlers 2/3/4
-Hammerwatch
-Bastion
-Trine
-Trine 2

Edit: La Mulana and To the Moon has some great music too

What game soundtracks are similar to Arcanum's? I'm looking for something using classic instruments but keeping it simple like arcanum which had like 4piece band for the whole soundtrack.
