- The movie is a re-telling of the origin story. While it is based on the first game it is not a re-telling of the first game.
- The game is a re-imagining of the original Ratchet & Clank using elements of the movie's re-telling of the origin story.
- The game will include many more areas/characters than the movie because it is just a longer format.
While it is a ground-up re-imagining, you will still see many familiar places/faces. All assets are being re-created, but that doesn't mean they will all be different. It doesn't mean they will be the same either.
There really isn't anything more I can say at this point. Both are set to release in 2015 and you will see more when they are ready to show. Stay tuned!
