A good question. The problem with using a human character was I would have to conceive a person who could witness various historical events in a wide variety of places and have a stature important enough to speak with historical figures. I did not want to utilize historical figures as characters because I do not want to risk grossly misrepresenting a person for 30 hours and it is limiting.
Using immortal characters that exist “outside the rules” was the easiest way to go. It also allows the lead to witness the beginning of Colonial North America to the creation of the United States of America (a time span of 181 years if you discount Roanoke Colony). At the same time, the characters are neither worshipped or demonized. They have no special titles. They existence is shrugged off, following the lines of magical realism where ‘unnatural’ and ‘fantastic’ concepts are accepted as mundane and realistic.
The lead character is not a world-saving-teen, he is not even a leader or some beloved hero that screams “This is America!” His journey is about “discovery” as he follows a chain of events. Yes, all major events and campaigns are based on historical events and battles – like the Battle of Monongahela, Battle of Fort Ticonderoga, Battle of Long Island.
He does not change the world – the world changes him.
The concept is bizarre for a game, but hang in there!
