Do you have anything to compare between all the VV's?
I like how in VV3, the children choose a spot that is far away from our main view to go to the toilet. It can be a bit disturbing knowing that in Virtual Villagers 1, the children pee on our flowers, and on VV2, they choose the firewood to wet.
I also love the amount of detail put into VV3. As soon as I loaded up the game for the first time, it felt like a completely unique island. There was practically detail packed into every seperate pixel!
Another thing I also noticed was the clothing. In Virtual Villagers 1, the villagers wore older, and a little bit plainer clothes. Gradually as the game continued into the sequels, you could see how much the clothes had changed. I love how VV3 has lots of newer, fresher and brighter clothing in store. I also love the leaves in the hair!!

So that is my opinion...what is yours?
