Enshrpuded is a great suggestion. You can ignore quests unless you want to expand your plot. Just pick a plot of land and start farming. Go out into the wild to find new stuff to plant. Unfortunately there’s not much to do with your harvest except to make provisions to go play the rest of the game, but that’s how you find more things to plant. I had a great time designing the layout of my crops.
I once experienced this firsthand. The postdoc kept coming by, trying to find out how we were messing up something he had written a paper on. Eventually, he tried to reproduce it himself. No one could reproduce it, not even him.
