Also I want to give props to Activision here. I know they get a lot of hate, but the fact that they agreed to release the classic games on GOG without DRM at good prices deserves a mention. (That's how I came to play King's Quest, having never played it as a child.)
That and them finally agreeing to let The Silver Lining fan project go ahead, and giving Telltale the rights to a new King's Quest game. I'd say Activision is looking after Sierra fans pretty nicely.
