Alternative Vector: Mr. Madison's War (2020)

From publisher blurb:

In 1812, after years of provocations between the young United States of America and the Kingdom of Great Britain, war finally erupted between the two old adversaries. Three years of fighting and bloodshed followed, to culminate in 1815 in what most historians consider to be a draw.

But what if it didn’t happen that way?

What if instead the Americans, after losing two pivotal battles, suffered a decisive defeat by British forces at the Battle of New Orleans? What if as a result the British reoccupied their former colonies; several American states decided to return to the English fold; the slave trade was strengthened; and a new Indian homeland was carved out of the cooling corpse of the Great American Experiment, led by a wily Native who wasn’t killed when history says he was?

Then you would be in the world of Mr. Madison’s War. This installment of Alternative Vectors, an alt-history mini-campaign using the Cepheus Engine and the Original Science Fiction Roleplaying Game (OSFRPG), allows players to become part of a history in an America that never was — but could have been.

The campaign features an overview of events leading up to and after the war; an abbreviated character generation method; an expanded equipment list, terrain movement modifiers and wilderness events; and options to customize a character’s base culture.
