So GOG it's pretty much the second PC gaming store, and a big hub for pc gamers.
It's DRM free, and usually offers some cool digital goodies.
To be honest it's my prefered platform for PC games, and voting there can get some newcomers to the franchise, specially for pc gamers that don't even know the franchise (that also like old games, that was GOG's target).
