STMarket
I was looking for some relevant dates and numbers in history and stumbled upon an old addon idea that had been lost to time. STMarket allows you to create 16 generic products from 4 different departments, box them up, and sell them for cash. Raw materials are bought in randomized packs of eight, and each product takes a different number of materials and amount of time to make. STWholesale might be a better name for this one, but I didn't think of that back then. You can play with this one right now as a Supplier on The Big Apple!
