Hey there, I would suggest trying out my other game in the series that just got it's full release today(!). That should give you some sort of idea what to expect. I tend to try and end each character's storyline off in some definite way that doesn't leave a person hanging. The NPCs are the ones gaining, you as the protagonist fascilitates the gain/expansion/insert fetish here.
Oh, and check out my discord if you want to chat a bit more, or if you have ideas you think would be exciting to see in a new game. The Adventures of Joseph Earnwile is so far planned to have at least four chapters.
