Absolutely JohnnyWylder, I have been asking the same thing for some time now myself. Yams and Wheat are another two I would like. Then there is also potential to expand upon other renewable food sources using the animal pen. For example, shoebills could produce eggs, goats could produce milk, there are a lot of exciting possibilities.
That is incredibly nice of you to say, thankyou so kindly Archivist! And Stelagel, I agree with you that the small trees which five us vines do look like banana trees. Grapes would also be so at home in the cool temperatures of the Highlands and the Tundra biomes. Thankyou to all three of you for some outstanding ideas!
