""The most significant thing that I did in terms of research was to find published accounts of the actual diaries of people who travelled the trail,” he explains. “I took several of those diaries and read them all the way through and kept track of the things that really did happen. I also kept score so I could get a sense of the frequency with which certain things happened: what percentage of the days were bad weather, what percentage of the days were they low on food and things like that.” Another consequence of the research was the sensitive portrayal of Native Americans. When reading old accounts Rawitsch was surprised by just how often Native tribes intervened to offer assistance to travelers that were struggling along the trail. This was something he hoped he could insert into the game to combat the negative stereotypes that were prevalent at the time in other media. “We were very concerned about the way Native Americans were portrayed, because the schools that we taught in had significant populations of Native American students. In the diaries I read I probably should admit to being surprised by how often people wrote about the help they received from Native Americans who helped them understand where the trail was, where it went, what kind of food along the way was edible and which would make you ill.” This manifested itself in the game as a new event that could occur when players were struggling. Native Americans would approach the party and offer help by sharing food or supplies with the settlers."
