Continued from my previous post. Sorry about being so long-winded.

(3) Isola is a big island. It has fresh water, both in groundwater and flowing streams. A body of land must be pretty large in order to have supplies of fresh water; otherwise, rain falling on the island would just wash off directly into the ocean. (Why did people drink coconut milk on all those tropical islands? It was often the only source of fresh water they had.)

So there's plenty of room for a large, mysterious interior as the island seems to have. In the end-game time of VV1-3, along with boats, the villagers could form exploration parties into the interior. What could they find? Ruins from the original inhabitants, the lost villagers who've disappeared/been kidnapped/went crazy and ran into the woods, strange creatures, abandoned mines, extensive cave systems, crashed helicopters...there's much more but that's all I can think of off the top of my head. This could be the real end of the trilogy, when the villagers have enough of a surplus to send people with lots of food into the interior to rediscover the lost civilization or rescue the kidnapped children or restore the ruins or at least answer all those crazy mysterious questions about the island.

That could be quite a task. Micromanaging villagers on all four coasts so they can send food and tech points around so select villagers can be sent into the interior to uncover the ancient ruins. It's probably too much to ask for and I'm not demanding that the whole thing be made, but whatever good ideas are there, please use if you want them.
