The fact that they said you could change between the soundtracks in the menu almost makes up for the fact that from what we saw, the first cutscene's animation is abysmal.
Because I found Perilous Journey VERY difficult to take seriously when it sounded like it belongs in a children's cartoon with its extremely silly-sounding BOINGEDY-BOING techno tune. I'm referring to the CEA playthrough of the PoA when the remaster Perilous Journey kicks in.
And did I mention the opening cutscene's animation was abysmal? Oh yeah, I did.
Well let me go into detail. Captain Keyes looks like he's about to break out into derpy tears the entire time, while Cortana jerks all about like a robot with a face made of steel.
I'll just leave this here.
