We don't currently have plans to release the soundtrack on GOG, but we might consider it in the future if there's enough demand for it.
For now, you can also purchase it directly from the official Trine soundtracks site (available in both MP3 and FLAC): https://trinesoundtracks.com
- Frozenbyte support
Looks like you guys just stealth released some OSTs finally?
Edit: Appears they were, saw on gogdb.
Added to database 1-14 Trine Soundtrack
mp3/flac Trine 3: The Artifacts of Power Soundtrack
mp3/flac Trine 4: The Nightmare Prince Soundtrack
mp3/flac Trine 4: Melody of Mystery Soundtrack
mp3/flac Nine Parchments Soundtrack
It would be nice if these were in a complete package, it's kind of difficult to figure out which game comes with an OST and which one doesn't. For example, Trine 1 comes with the OST. So, why is the OST for sale? I'm guessing that the OST isn't included in the "ultimate" collection so if you buy the collection you'll have to purchase Trine 1 OST separate.
Edit #2: I bought the ultimate collection and it DOES have the OST, so I'm not sure why it's for sale. It requires you to purchase Trine 1 in order to buy the soundtrack, yet Trine 1 includes the OST (even in the ultimate collection). I guess it's for legacy buys pre Enchanted edition. Thanks for bringing us the soundtracks, appreciate it.
