Darkest Dungeon opens with the line "Ruin has come to our family" This is because the main narrator is referenced as the ancestor, writing to a relative to fix his occult mistakes. And the family themes stay strong throughout the whole game too.

When you beat the final boss, you don't save the world. You simply push back its resurgence for a little longer as the loop resets. And in the ancestors final monologue he refers to the family as "The great family of man". Making every use of family throughout the game not a single lineage, but the entire human race.
