I'm not sure how it could work but a map based on that concept would be entirely new and fresh.
Perhaps a meandering world divided into families (ie get your family members to finish). But to win you have to also pick up calamities, events, people, places and so forth that DECREASE your overall worth. On reaching your objective of your 5 family members the map auto-tallies who has the lowest value and if that's you then you win, if not then you're out and the others continue.
What think you?
