In my own playthrough, I used to earn as a fisherwoman (catch fish in the village and then sell it on the town market; note: need to obtain a fishing rod in a short quest in the village). I think I will just add a pond (or better river) to the town. Thanks for the feedback.
In general, the town path that played out for me is to work as a street prostitute -> lose husband -> earn a lot of money (with high sex skills group prostitution is unlocked) -> buy horse, house and anything else needed -> clean reputation at the temple -> find a new husband -> use horse to travel quickly between the village and the town, catch a lot of fish (with high fisherwoman skill) and sell it in the town (with increasing trader skill).
Unfortunately, there’s not much to do once you are skilled, rich and happily married, in this version. More to come.
