Organ Trail: Director's Cut (2012)

A structured westward route gives food, ammunition, petrol, spare parts and medicine competing claims on the same limited stockpile. Towns let you trade, take work and repair the station wagon, so arriving in poor condition changes what you can afford to do next. Party illness can become as serious as the undead. Treat the trip as a survival run whose people can die and whose collapse requires starting over. Its route is less free-form than FTL's, but the accumulating vehicle and supply problems make each stop consequential.
