I spent some time (well, ok, over 4 hours) late last night playing Nova... incredible game so far, and I'm sure I've only just scratched the surface. But I just have to say that whoever chose "Mars" from Holst's Planets Suite is a genius. :-) The menacing tone of this song really helps set the mood for the game. I usually turn intro music off on games like this, but this one will stay on.
