Definitely want mass harvesting put to good use. I've built an orchard now I'm in the process of building a vineyard.
Basically want my sims to go into wine and beer production.
would love to build a wheat or corn maze.
I would love farm animals, with the option as keeping Cows and Pigs and such as pets, or as livestock.
I would love actual Harvest Festivals. I have this medieval save where this noble family, who holds the south-western region of the kingdom, and it would be cool, if during their harvest times, they threw a week long festival. Bake offs, Eating contests, Mud wrestling, Jousting, Keg Drinking Contest, Wine/Ale tasting Scavenger hunts, Music and finish it off with a Grand Feast.
