VetMichael: Are games on GOG ever dropped off the list? Or is it an ever-expanding smorgasbord of Good Old Games? If the games are dropped, is there any warning so we can scoop it up at the last minute?
Usually, yes, there has been a warning. I think Hostile Waters was the only one dropped without one (nor an explanation). The reasons for dropping anything have - as far as I know - always been rights/licensing issues.
Colin McRae 2005 and
Toca 3 were dropped due to the publisher's license to use the cars having ended.
Operation Flashpoint had some licensing troubles with the music, I don't remember exactly what the issue was with
Republic: The Revolution,
Obscure and
Hostile Waters. Original War was dropped, but came back. Moto Racer 3 was dropped for a while due to having some technical problems, but I believe it was made pretty clear that it would come back as soon as the GOG team had worked their magic on the game to get it working (or completely remove the DRM, one of those).
I probably missed a couple games, but those are the ones I remember.
Nothing have ever been removed from people who has already purchased the games, though GOG has stated that the possibility exists that a game MAY be removed from your account, and thus recommends that you make a local backup.
