Short version is that Blizzard’s removal of Warcraft I & II is the first case to be in the scope of GOG’s (re)commitment to game preservation since GOG published that commitment.

Good for GOG, but I don’t think having games still available after they’re delisted is special. It would have been news if this didn’t happen.

Edit: I mean you can still download the games, if you’ve already bought them, not that you can still buy them.
