That's a bunch of really glowing reviews of the hands-off demo. Hopefully that level of quality reflects on the final product, and throughout, not just in one area or act. They're making a MASSIVE world that, from all accounts, dwarfs Skyrim, so it will be a tall task to populate the whole area with interesting things to do and encounter. Hopefully CD Projekt RED can pull it off. I have faith in them.
It will be the Citizen Kane Casablanca of video games.
