Sins of the Fathers is a point-and-click adventure game, played from a third-person perspective. Its story unfolds, mostly linearly, over a sequence of "days", each of which has a required set of actions which must be performed before proceeding to the next day. However, within each day, play may be nonlinear. Throughout the game, a running score is kept as new challenges, both required and optional, are completed.
