Oh, I love Riven's music. And I know what you mean by the saxophone--especially for the 'Fissure' track. It's so melancholy, yet so beautifully. I love Riven's music almost more than anything else I've heard.
Jack Wall is great, though. Although I agree with Alahmnat--some of Exile's music was a little bit too theatrical, especially the latter ones with Saavedro. And I really would have liked a more peaceful, conclusive credits song in that game--not the singing like was in the intro. Still, the main theme of Amateria is one of my favorite songs ever. So, I'm REALLY looking forward to Revelation's music.
