I seem to be just a little bit behind in these polls because two VV games have been released since they started, but here's my comments anyway.

My favorite event in VV1 was a mysterious potion that one of my adults drank to become a child. Since he was an elderly master builder at the time, it was a huge bonus for my village!

I like the Biggles visits in all the games, even though he rips your village off sometimes. It's cool to see a friend popping in from time to time.

I like any events that result in someone liking to run. The person in VV2 (or is it 3?) getting chased by a bee is also a nice lesson for real life people.

I loved the event in VV2 where someone gets bumped on the head. That happened to me right away in VV2, and the person who got bumped suddenly becoming an adept scientist was a huge help. She (who I renamed Terra like in Final Fantasy VI) was my first Village Elder! Whee! It turned out that my amnesiac was the adult that the children got left with. Oopsie!

I don't like the events that result in someone mysteriously vanishing though. I know someone's gotta face bad things to make any game realistic, but it always seems to be the most talented villagers that end up leaving...
