I remember in a thread awhile back one user was upset about the digging 'peat bogs' because of real-world environmental concerns. What if peat bogs were replaced with mushroom groves?
I would LOVE to grow/harvest mushrooms. I like cooking a lot and it's annoying that while I can grow or harvest most ingredients, mushrooms require a trip to a grocery vendor. There's already patches of mushrooms in the graphics of certain places, why not make them harvestable!?
