Even in reality, life as a farmer is hard work and often little profit. This is especially true in times of war. The developer is not that far away from reality with Penny.
Next remember:
Penny is all alone, apart from her good-for-nothing husband. Anyone who has followed the in-game story closely will also know that she recently lost her entire family. Her parents are dead, her sister's whereabouts are still unknown. From now on she became the only one who still serves the farm. It is rather a miracle that she did not get completely run over. With this background, she is definitely one of the most interesting LI. I'm excited to see what else awaits us with her
That is all nice and fine. That is exactly where the MC comes in. He helps her out, does several tasks which are time and energy consuming (field work, wheat grinding) and as the story develops he even helps her to lease some additional land from Giron. The MC hires the mercenaries required for protection, builds the chicken coop, renovates the barn, manages the mill repair and digs an irrigation canal and builds a pasture for cow breeding and milk production.
Normally this all should allow Penny to become profitable. But it doesn't. Th MC now just has more manual labor to do as it seems. Because now he has to check for eggs and sell them, too...
It shouldn't matter if Penny gets her vegetables from the MC at Monday already or at Friday as long as she gets them in time. And the wheat grinding should now be done by the miller, tbh. That's what this guy is hired to do. It was said that he would bring the wheat to Penny's house. So the wheat should actually never run out there. The MC could then grind some additional wheat if he has time. But the farm shouldn't depend on it anymore to be profitable already.
And originally the bread on the sideboard was meant for the MC for his own use. This also seems to have changed now.
Honestly, as of now it would make more sense if the MC would store his harvest in crates in front of Penny's house. Each Monday Penny should then take a fixed amount of vegetables out of them and sell them to Lucius. The miller should daily take a portion out of the wheat crate and grind it. There should be a defined amount for self sufficiency and one for making a decent amount of profit. Like it is the case with the potato minigame. The MC has then just to ensure to keep all the crates filled. There could also be a crate for the eggs. In that case Penny would directly get the money for selling them. Something similar could be done with the milk or even chicken meat.
Chicken and cows normally produce manure. Putting manure on the fields before planting the seeds should significantly increase the harvest.
What I'd like to see is the MC building some kind of automated watering system that waters the fields once per day. This would not only ease his work but also the one of Penny and her workers.
And I'd like the MC to be able to either buy the seeds he currently needs from Penny or from Lucius.
