I chose to let him have some samples or whatever and got a level of medicine.

I had an event about a DREAM of growling in a cave... I chose to look at the gold and nothing happened.

I usually choose to open or not open the crate based on the description. Rotted seems to mean rats, weathered means +tech but sick villagers, watertight means a new kid or three...

I had an event with a red potion on the ground. I had the villager drink it and although it said 'he felt different' nothing seemed to happen. He looked the same and stayed apparently the same age. He was a child at the time though.

Oh, I got an event that broke my heart because I'm a softy. I found a struggling moth and chose to help it. That made it weak and it fell into the sea... what would happen if I chose the other option?
