I really like the whole animal/livestock idea. Maybe the island isn't so "tropical" and some cows, chickens, horses, etc. can be added.

Also, there has got to be some way of keeping the builders going. It is really hard to master that skill once all the huts are built, etc. They work on the huts...but don't seem to gain skill like the farmers and researchers. Maybe it is just me?

I'm sure whatever VV3 turns out (new and old stuff) is going to be fantastic...just like the first two games!
