An alternate history can set the circumstances from which a war game begins. Events after the chosen divergence belong to the scenario rather than the historical record. Some changes are chosen to make the game work, while others follow from the assumptions under test. Keeping those roles separate prevents a simulated outcome from being presented as recorded history.
