I think I heard some neat adaptive music ideas when they showed the tech demo. Like, I think one of the premises of the game that you learn early on (mild spoilers ahead) is that the singer (main character) loses her voice. The battles consist of real time action, and there's this "freeze time, plan your moves, and press a button to execute" mode. What I heard in the tech demo, the music is playing and it's all fast and tense, but when you enter "plan you action" mode, the music changes to this slow, lounge singer-y type thing ... and you can hear the main character singing. Which really struck me. She loses her voice, but when you're planning your moves, in other words "in your head," you can hear her voice. Because we all hear our voices in our head, right? It was really profound to me for some reason, and sounded beautiful.
And a step further than that, I think I heard that the two songs were playing at the same time, actually as ONE song, but certain layers of the music were active at one point, and not at another. Like all that adaptive music stuff I've bored you all to death with before (

So there's lots of reasons I'm excited for this. If Bastion is anything to go by, the story will be excellent. The art direction is absolutely superb. The music is excellent, as well. The gameplay looked pretty cool. But if the studio actually went ahead and did some neat technical stuff with the music, like adaptive music techniques, then I may lose my goddamn mind over this game. But even if they don't, I'm sure I'm still going to love it.
Fingers crossed.
