Face ethical dilemmas. Do you really want to spend money on that proper hotdog meat for the festival when you have so many resources lying around?
Gather valuable resources & craft new items. Expand your Graveyard into a thriving business, go ahead and gather valuable resources scattered in the surrounding areas, and explore what this land has to offer.
Make business alliances. These dead bodies don't need all that blood, do they? Why not sell it to someone who can put it to good use. Same for body parts. Hey, it's being efficient with recycling!
Explore mysterious dungeons. No medieval game would be complete without these. Take a trip into the unknown and find useful new ingredients which may or may not poison a whole bunch of nearby villagers. Capitalism.
