Here's an interesting history on how The Oregon Trail was created by three teachers trying to figure out how to get 3rd graders interested in history.
Rawitsch debuted The Oregon Trail in his classroom on December 3, 1971. He rolled the teletype into the center of the room, and the students gathered around. The machine churned out a roll of paper with questions like “How much would you like to spend on clothing?” When a kid typed in a number, the machine delivered a new question, along with an update on his or her condition. Some imagination was required. In order to hunt, students had to type the word bang. If they typed the word quickly and accurately, the machine responded: “Good eatin’ tonight!” If they faltered, the machine sniffed: “A little slow on your Colt .45.”
