Well, you can get the main game for free, but Sierra also decided to release Dark Conspiracy for free to anyone with a copy of the game. Therefore, shouldn't Ground Control be free on GoG, with Dark Conspiracy?

hey, propbably yes. But server cost etc isn't something they want to cover for free games.

Also thhey put a lot of work (GOG) in their released games to work with modern PC or x64 systems. Also they give people a lot of content beyond only a game. 5,99 is imo fair deal.

IGo to steam community and ask people what steam does for old games. NOTHING. If game is only win98 they will release it as that.

Real test for GOG devs will be System shock 1/2 and Vampires Bloodlines if they will release it.

Both games are very buggy at their times and system shock 2 have real problems with modern PC.

Also you don't wat to cut some cash for devs and their great game ?

I look forward to the day the System Shocks are available with bated breath. Vampire Bloodlines was one of the more fun games I've played, and one of the most buggy ever, so that definitely would need work, but if they released it too...nice.
