babark: Wing Commander was free at some point? When? By who? Where? :D
To be totally exact, though, gog isn't selling Wing Commander, it is selling a Wing Commander 1+2 pack. :P
Pack or not, Wing Commander 1 was given for free on WCNews. Perhaps it was abandonware, but here what it is still said on that page:
"... There Was Wing Commander I
For our final update of the night we are proud to present, in honor of its incredible 20th anniversary, the game that started it all--the original Wing Commander, available for download!
Wing Commander (121.6M)
If you're new to the original Wing Commander, be sure to check out our online copies of the Claw Marks magazine and blueprints posters... and if you're looking for an additional challenge you can pick up the Secret Missions
Please note that this is adapted from the Kilrathi Saga version; although DOSBox and related developments would make the original easier to run on modern computers, we are only permitted to post the specific release included on a 2000 PC Gamer coverdisk. I was able to play the game easily on a Windows XP machine while Kris had trouble with the speed limiter in Vista. I am confident that the Tech Support will rise to the occasion and help keep this version of the game running--so give it a try and post your problems so we can work it out.
Finally, to other webmasters and magazine editors: this is not a freeware release of the game--anyone wishing to include this download at their website or in their publication must contact the rights holders themselves. "
