You could argue the concept of open world games date back to 70s with Dungeons and Dragons. The point I was making was that Shenmue introduced the world to a new way of approaching game design -- even if not all of the ideas were truly unique it did still package them in a way that hadn't been (successfully) tried before. Which is why it's such a memorable game.
But the concept of "open world" could date back to Ultima RPG. You could set Ultima VII under an "open world" genre.
