Prophecy shouldn't be a problem. All I needed was nglide and a small graphics fix to play the game on a Win7 machine without any problems whatsoever.
Hm, I'm wondering if GOG got the Gold version which includes the Secret Ops episodes, but it wouldn't be too tragic if they didn't. a) Special Ops is ok, but it's pretty much just a collection of dogfights connected by a very basic storyline, and b) you can ge t the whole thing for free on Wing Commander CIC. Their package even got updated graphics.
Academy and Armada, hm. Maybe it would be best if those were bundled together. >_>
The Darkening, though? I sure hope they take their time with this. As I remember, that game was very buggy and crash-prone. Nice to see it here, though, even if it's mostly for the movie sequences. I gotta have more Walken around here, baby! XD
