The game farming should depend on seeds and quality of them, as the embark option will include the hability to select what to bring it would be great if you needed actual seeds to plant your crops, you can rely on your hunter and harvest food from the wild plants at least untill you can get yourself some crop seeds,
the seeds should have also different tiers and they provide results depending of it. for instance a
D quality seed would provide a normal quality amount of crop and have a chance to not provide any meanwhile an A quality crop should provide a larger crop and no chance of provide none or suffer illnesses.
seeds could be obtainable from the biome harvesting wild plants and drying them
this introduces a new feature for the farmer, the farmer workshop, which is a table used to dry plants and produce other objects used in the farm field as mix fertilizer or prepare poison to destroy plagues from the plants.
also crop quality will affect food quality, better food quality will have an effect on how earthlings work, been better making them work faster, live longer, to the impossible, see the invisible ROW ROW fight da powaah!..
