Hey that looks cool.
My "wow" moments would have to be the following:
Command's message in sm3-10 (Apocalypse) - "Capella has gone supernova! Repeat, Capella has gone supernova!..." : completely unexpected turn of events there; while flying to the node I was really thinking hard about how the GTVA would respond to this.
(didn't know that the game ended there)
Snipes' message (of course) in loop2-2 (Into the Lion's Den) - "Dive! Dive! Dive! Hit your burners, pilot!" : I had my headphones cranked up to full volume and this completely startled me - enough to make me jump out of my chair for a second
-, after which my Mara got smacked ten thousand meters away.
sm3-09a (Good Luck) Subspace mission in FS1 : really cool background, I was just looking around for a while before going about my objective.
sm1-08 (The Sixth Wonder), arrival of GTVA Colossus : I used to think the normal destroyers were big, but this completely blew me away by its sheer size. After Command told me to depart, I was flying around the ship for five or so minutes, trying to see exactly how it was structured.
