Sins of the Fathers is a point-and-click adventure game, played from a third-person perspective. Its story unfolds over a sequence of “days”, each of which has a required set of actions to be performed before proceeding to the next. In this way, the game proceeds mostly linearly, since the puzzles on a given “day” must be completed in order to reach the next day. However, within each day play may be nonlinear. Throughout the game a running score is added to as new challenges (both required and optional) are completed.
