GOG.com is a division of CD Projekt, a Polish game publisher/developer, whose CD Projekt Red is known widely for the "Witcher" RPG series. GOG basically licenses classic games from other publishers, removes whatever digital rights management (DRM) systems that are in place and provides a layer of compatibility for newer operating systems, all for a couple price points: $5.99 and $9.99 (Though they usually have weekend sales and promotions). There's also a few freebies to pick up. GOG also likes to pepper its releases with bonus content such as wallpapers, full game soundtracks, avatars, game art, strategy guides and all sorts of other things. And there's no download limits!
So now you're probably going to say Okay Cy, this sounds pretty good. But what games do they have that could draw me in?.
Let's see:
Fallout series (Fallout 1, 2 and Tactics)
Duke Nukem series (Duke Nukem 3D Atomic and Manhattan Project)
Far Cry
Serious Sam series (Original versions)
Postal series (a personal favorite)
Empire Earth series (Empire Earth, Empire Earth II and regrettably, Empire Earth III)
Unreal series (Unreal, Unreal 2, Unreal Tournament and Unreal Tournament 2004)

and the Tex Murphy series (Mean Streets, Martian Memorandum, Under A Killing Moon, the Pandora Directive and Tex Murphy Overseer)
In fact, let's take a look at the Fallout series as released on GOG, compared to Steam:
