The Oregon Trail is a game that came out in the early 1970’s with the intentions of teaching players about the realities of frontier life in the 1800’s. The game requires players to try and keep their family alive long enough to make it across the Oregon Trail. Players must make decisions to deal with things like typhoid, wagon wheels breaking, cattle being stolen, etc. The game is extremely difficult to most players because each decision that is made could effect the course of the game either directly after it is made or a long ways down the line. The Oregon Trail has also spawned a variety of spin-offs, such as The Amazon Trail, The Yukon Trail, and even parodies like The Organ Trail. It has become an icon in the world of gaming.
