I think like others have said this show is a copy of many of the Indiana Jones ideas. I don't know about copying a computer game though maybe we should say that Tomb Raider is also a Copy of Indiana Jones but with a woman playing the lead role to avoid being called a knock off.
I don't analyze the shows I watch too much for historical accuracy as this is a low budget TV show and not a documentary. The corn thing that one of the commenter's wrote about is a funny one. But not too inaccurate as Corn was a name used by Europeans during the Time of the vikings to refer to Grains and is Anglo-Saxon in origin. It was an American thing to refer to Maize as Corn. SO their use of the Word Corn is correct but maybe confused the writers of that particular episode
