Stamina is now ten times as cheap in terms of food. I.e. you now need to eat ten times less compared to before.
Probably way overboard.
The FEP variance bonus has, to compensate, been doubled.
It probably needs even more of a bonus.
Fish is now a limited and localized resource, working in the same way as any other localized resource. You should notice fish jumping in the water if the area has fish. (update your clients, plx)
Fish quality is determined primarily by map data. The Q on your fishing gear can only reduce fish quality if lower than the fish's.
The people that need the dex will probably hate you.
Animals are now somewhat rarer.
I predict playing getting boring fast. Though I'm sure it will not make bears and boars not spawn in the village grounds.
Growth time on crops has been doubled, now taking ~two real (six ingame) days to mature.
More pumpkins for the same cows joy. Not.
Shift-planting now works with seedbags.
Don't worry seedbags are still useless.
