Ok. I definitely never said anyone was going to see a movie by themselves that they don't wish to see. No splitting hairs. Maybe you were projecting something that was not said? I just say it is reasonable to presume that in a smash blockbuster hit millions are going to be spending ticket money to see something they have not experienced the inspiration from.
Jaws, Gone with The Wind, and any book based screenplay if we want to go back to the most common source inpiration for screenplays in cinematic history. I don't even know how to reasonably claim that one as a number just like any other, but they would be included in the millions seeing the movie that have never played. I did not think you were arguing on a hill, which is odd to me, but rather just not being reasonable that millions of tickets sold to a movie might have people who are not into the lore of the inspiration enough to have played the game.
