Well, it would be nice to know what happened to Admiral Bosh and know the truth about Shivans. User made mods are giving plenty of ideas but they are not as good as FS and FS2.
Playing last mission of FS my fighter exploded the same second, the rest of the wing finished the last reactor of Lucifer. So I died but won. And I still remember playing FS2 - how shocked I was with supernova ending. Trying to escape the shockwave... didn't make it (first time, anyway) :-)
But my greatest dream is to find Wing Commander series on GOG one day. In happy day, as a lucky Amiga user I played only first part of that game. I started with German version and couldn't understood anything from briefings :-) so I was using a map to know where to go and shooting anything red on radar. Playing again English version and enjoying the storyline was great pleasure.
Nova days I tried to play WC2 using DOSBox but it isn't working well, so I hope GOG will support me in some time...
