Well, you have to imagine that some of these tracks have been written with the context of the story in mind, or that segments of the story will be directed with the pace the song in mind.
It reminds me of this scene from Attack on Titan (which he also composed), where Mikasa wants to die, and there's a slow build up with the music for well over a minute, but in context to the scene, it made it feel more emotional when the track picked up pace as she remembered Eren's words and changed her mind.
I wouldn't mind if it was set up like that, but there's a difference. First, that was a piece, not a song. The way they're structured are different, and what they are building up to is different. Second, that peice isn't the opening peice. They made that song out like it was the theme song to the whole game, like Sanctuary or Simple and Clean. That's a completely different setting for a song than that scene.
Yes, I was just illustrating that it can still be nice if it suits the context of the scene. However, as you said, it's not a saong, a.ka. no vocals. This would be a more suiting example to what you said:
It starts from 0:19, then around the 1 minute mark it slows down in pace, building up to the moment that occurs in 1:39. Then the vocals start. The vocals last until 2:11 (32 seconds) in this particular scene. And that seems fine, as the music that continues is still very suiting for the action oriented moment. And from what I remember, the length of the tracks, as well as the various segments within those tracks were some times altered to suit the scenes they played in. The same might happen in this game. Not sure about main theme of the game though. It might mean that it's going to play often. But that might also mean we'll get different versions of it to suit the scenes it plays in.
I'll say that I won't doubt this man's talent until he disappoints me.
If you go to the actual song the vocals start at the 2:25 mark. Great reference though, pretty much spot on.
