I'd like to see eggs, arrowheads, beads, and flowers as collectibles! It would make it seem like there really used to be another tribe there before with the beads and arrowheads!

Also, what about making some more island events? Maybe have a vial of liquid that makes adult villagers act like kids without being kids? That would be sooo fun to watch!
How about some new fish designs? Maybe have three fish types instead of two? Also, what about hunting??? Hunting would be soo cool!
While it would be cool to see villagers sleeping and stuff, it's impractical on several different levels. It would slow food/tech point production. Plus, how the heck could they all fit in those huts???
Could there maybe also be a way to change clothes again? Maybe like a sewing table? Also, maybe while mothers are tending their babies they could work on clothes for the babies? And why aren't dads able to care for the kids too? Babies don't need to be nursed all the time! Let the moms have a break!
To keep the third game from being too similiar to the first two, maybe ditch the waterfalls and special fish this time around? We've already had a fertility fish and an algae-eating fish as puzzle pieces! Let's find some new stuff! I'm not saying I hate those features, but it would get kind of boring if the third game had a waterfall and special fish again!

I love the idea of hunting! That could be a new food level! Also, what about growing banana and pineapple trees?
Of course, I'm sure we all want to know what the different artifacts all have in common! I'm pretty sure that the GC is the magical person refered to on the wall in VV2. And what happened to Tofo and the parents? Maybe if we find them, they should be skeletons? After all, by the time VV3 is released it would be very unrealistic for Tofo and the parents to still be alive! Unless they stayed alive through some type of magic...
