This is a good point. It would be easy to add this. Some of the worlds are already suited to growing oranges. (Oasis Springs, anyone?)
As for juicing and smoothies, I'd like to see them such as in a broader pack with other activities. I agree that we really have room for farming. We don't have many of the large-scale crops such as corn, beans, wheat, oats or barley. As someone else mentioned there are still some fruits that are missing. Mango, anyone?
Modern farms also harvest solar and wind energy which sounds like it would appeal to the team. (Power your own off-the-grid lifestyle and sell any excess energy).
Anyway, yes, I'd also like to see other types of juice. That seems easy to add. I know they polled us in the stuff pack poll. Something like that might do better in a different pack. Farm-to-table seems like an obvious theme along with the animals.
