The Bloody Forks of the Ohio is a tabletop indie RPG set in the Ohio Country in 1754 -- a moment of historically vital importance. What happened there was the proximate cause of the Seven Years War, a minor fight in the woods between a few hundred men producing a global conflagration that involved all of Europe's Great Powers and warfare over three continents -- North America (where it was known as the French and Indian War), Europe, and India (where France still contended with Britain for control of the subcontinent).
The history is this: three powers -- the Iroquois, the French, and the British -- all claimed the region. The Iroquois had survived mainly by playing the British and French against one another, but their hold over the region was tenuous; the Delaware and Shawnee who settled it owed ostensible allegiance to the Six Nations, but were not themselves members of the Iroquois confederacy, and not inclined to take orders from Onondaga (the Iroquois capital). The previous year, soldiers dispatched by the governor of Virginia had built a small fort at the confluence of the Ohio, Monongahela, and Allegheny rivers (a place we now call "Pittsburgh"), but the French, discovering this intrusion into what they considered a part of New France, set them packing, and built Fort Duquesne, a considerably more robust fortification.
