then, other considerations
1) the stats might be not for 1 building, but for the general production
2) set some starting condition....it could be great if the village starts with nothing (no house, depot etc etc) but even without plants and animals
3) in future, i'd like to see a "seed system". If you have seed you can plant crops. but not like in banished, where if you buy a seed you can plant everithing u want....seed must be a finished number...
for vegetables could be a secondary product of crop (pumpkin seed etc) for cereal might be cereal itself, so you have to choose how much plant and how much eat
