Consider This: Historical Events as Game Missions
As a video game, Assassin's Creed III relies on completing missions to drive the plot forward. Many of these missions are significant historical events; things that shaped or changed the course of the American Revolution. However, many times the plot takes precedent over historical accuracy. Sometimes the fiction overtakes the facts.
For example, one of the missions within the game is a retelling of the Boston Tea Party. Occurring on the 16th of December, 1773, members of the Sons of Liberty dressed as Mohawk Indians to board cargo ships and dump tea owned by British backed companies. George Hewes, a member of the boarding party, describes how as soon as it was night the group “Immediately dressed in the costume[s] of an Indian” and “took out all the chests of tea and throw them overboard.” After “about three hours” their job was done. A point that Hewes specifically mentions is how while they “were surrounded by British armed ships…no attempt was made to resist us.” Watch the video of the game mission, and you can see how it contradicts the historical account, especially in the terms of violence.
Assassin's Creed's The Boston Tea Party
By the nature of this type of narrative, every event in history that your fictional character interacts with is in someway altered. Consider how this scene depicts the Sons of Liberty and the British Regulars. Does it matter how the Sons are dressed? Does it matter that they confront and kill many British soldiers? Does this change the significance of the Boston Tea Party?
