GOG has been awesome since it launched in 2008, with a library of cheap, DRM-free videogame classics that's been growing steadily ever since. But there's awesome and then there's holy frikkin' awesome, and this deal with Activision and its huge library of great games is most definitely the latter.
The Activision deal launched with two great games: The Troika RPG Arcanum: Of Steamworks and Magic Obscura, originally released in 2001, and the 1993 Sierra adventure Gabriel Knight: Sins of the Fathers. Both games are selling for $5.99 with extras like hi-res wallpapers and forum avatars, and as usual are tweaked to run without hassle on modern hardware and operating systems.
The addition of Activision is exciting because of the potential wealth of new (old) games it brings to the party: Sierra classics like the King's Quest series, gems like Interstate 76, the Vampire: The Masquerade games... I could go on, but you get the idea. With everything from Homeworld to the Mechwarrior and Quake games marching under the Activision flag, this deal has the potential to be absolutely huge, for GOG and gamers alike.
