So, if you played the game without the context of the theme, sure you would subconsciously know, this isn't real, but that is true for any other game. You could also grasp that it is not realistic but being realistic isn't being real. So, you would likely never come to the conclusion that this was made to fit the theme "It is not real" and if you heard it was like you likely would for most games as not many look for a theme, you would probably be shocked.
