I would like to add my 2-cents to the argument about "pseudo-european medieval" and point out that there are several crops that are NOT european/old world (pumpkins, amaranth, casava, pineapple, breadfruit, peanuts, peppers, sunflowers, cranberries, and blueberries). Therefore, I believe it is within the realm of possibility that potatoes can have a niche in the game. I would also like to see some sort of bean/legume in the game, like chickpeas or fava beans (in addition to seeing potatoes)
