I understand, but there is no way he knows for sure that they are not the same. While I'm not saying they are the same ride, even though they look very similar, it is impossible for him to know that Mystery Mine is not the original plan for the Adams Family concept because of how Adams Family was never built. Yes, we know that FoF and RnRC are different because both rides have been built. The problem with this is that Adams Family was never built, so no one except the designers at the company making Mystery Mine would know if they were the same. You don't know, I don't know. The only way we could be 100% sure was if we either 1) worked for the company making MM and knew of the designs of both concepts, or 2) both rides were built, and then we could compare.
