I would love to see something in the new game that would allow you to complete a puzzle or clear a blockage (like the boulder in VV1 and the thorns in VV2) that would lead to another section of the island where your villagers could explore!

Perhaps the new area would have a new food source, room for more huts, if the collectibles will be reintroduced in VV3, there could be a series of collectibles only found in that new, secondary area. It wouldn't have to be anything large, just something new to look at and poke around in.

I'd also like to see more island events, even if they don't give huge rewards / penalties, just more of them would be a lot of fun!

And of course, the ever present request for more clothes / head types (and I throw my vote in for the removal of "helmet head" too!) Would be great if you could take them into the clothing shop and be able to fully customize their heads / hair and clothing - for a price of course, heh.

Can't really think of much else, as these games are just so good already, hard to improve on them
