I decided to look for information about when potatoes appeared in the Middle Ages. In the game we are presented with the years 1330-1350 (approximately). I don’t think they know potatoes yet. oh, sorry. here is the quote: "Cereal crops (except for rice, which was introduced into Europe relatively late), remained one of the most important products throughout the Early Middle Ages, since potatoes were introduced into use only in 1536, and became widespread much later".
