Ok, that was damn interesting. Firstly it provides definitive proof that the AE is not "just" farms, SFMAs and vanity projects. This is something that frankly would never appear in the actual game. And that's a strength of the AE rather than a weakness.
I loved M1. M2 and M3 not as much. And M3 has enough glowies to give @Kyksie apoplexy. That said, it was very atmospheric and oddly fun. I have yet to check whether being able to sight read music would help, because it's not a skill I possess so I can't really comment.
I'd recommend people try this to see something totally different, just don't go in with any expectations.
