100+ have never been used before in any game. They had a lot made for the first two Divinity games but didn't end up using them.
Still, isn't it still sort of cheating? Bringing some old stuff out of the closet? And what about the orchestrated music?
Unfortunately Kirill fell ill, they have done quite a lot of it before that happened though....some 50+ songs and the rest they remastered so it's not like we don't get any of it. As for cheating....well, they paid to have the music done and if they couldn't use it before I don't see why they couldn't use it now.
