This is a game about folklore, magic, and superstition with Colonial America as the setting. We can safely assume this was never intended to be considered an accurate historical portrayal.
On the reframing of American history. America is still a country of insurrection. I may also believe that America is racist, built on oppression, the genocide of indigenous peoples, and chock full of class/gender warfare.
However, in "a game" America can be just about anything. It can be as "politically correct" as it wants to.
Just like in the movies (National Treasure, Abraham Lincoln: Vampire Hunter, etc.) and other games (Deadlands, etc.) creative liberties are/were taken. I am in agreement if "a game" writer(s) and/or a gaming group choose not to curate a part of history. They just request for it to be labeled or identified as Flames of Freedom, the writers demand that it adhere to what they endorse for the game. That to me seems fair.
I do agree with the choices they have made and look forward to playing the full game when it come out.
Colonial Gothic, Pregens are interesting thematically and diverse, Grim & Perilous mechanics: AP simplicity and variety of results add a tactical element to combat, Zweihander compatible (Injury Cards, etc.), Coin mechanic, Alternate History (Supernatural America)
Game will be subjected to historical analysis and shenanigans.
Sensitive material for some players.
