Agreed. Beside the manual, which is critical, accurately recreating the gameplay will require extensive gameplay footage. Ideally, this will come from the same person so they can shoot the videos from a consistent angle so the graphics can be recreated correctly. They would probably need to do an initial playthrough video, then we can communicate about what additional footage would be required based all the different alternate actions that can be taken at any point in the gameplay. Also, that person would definitely need to agree to be involved in playtesting the builds to ensure the simulation is as close as possible to the original.
