I'll have to ditto the ideas for nighttime, weather (but not snow - this is a tropical island after all), bad weather damaging huts and generally causing other setbacks (similar to the wave washing junk back onto the beach in VV1), parenting points while taking care of children, men taking care of infants as well, a school with dedicated teachers to raise the skill sets of the children, and others.

My suggestions:

More collectibles! Flowers, feathers, and whatever various pretty things people could find on a big tropical island. Not only can they find them and get points as in VV2, but they could be used to make art and jewelry. It'd be fun to be able to decorate the huts, have elders wear special headdresses or necklaces (using tech points and collectibles), make displays, etc. It'd be something to do at the end of the game once the puzzles are all solved, the population is maxed out, the cemetery is full, and so on. There could even be dedicated artists. There wouldn't be many at the beginning of the game when people are more interested in food and general survival, but when everyone is full and comfortable and the population is large and stable, why not?

Boats! The villagers in VV1 came over in boats. The villagers falling into VV2 carried the tale with them and the lost children's parents sailed away in boats. They have the resources to make boats, especially at the end of the game with all those tech points that have nowhere to go. The villagers have probably passed down the legend of how their original home was destroyed, and they'd want to have boats to be able to flee, just in case. It also opens up a lot of other possibilities, such as the villages of VV1 and VV2 communicating and trading, people sailing out for extended periods to go fishing (with varied results, including feasting and partying if the boats return laden with food), and even other story lines. It'd also be something to do at the end of the game when everything else is done. The builders can always keep busy building new boats.

I have some other suggestions, but most of them fit more into the "ideas" thread rather than this one so I'll put them there.

EDIT: How could I forget musicians? I play clarinet and I forgot. That's another thing, though. They could make musician instruments and play them in their artistic little villages.
