I 'd like to tell you about interesting experiment which was done by Taylor Danick. Once more I realize that the possibilities of people's fantasy do not have boundaries. And as an example is The Lost World. I visited this Sim a little more than 1 month. During this time it had changed. If you visit to this place you'll see:
1. The gorgeous re-creation of an ancient World atmosphere.
2. A lot of ancient animals which could react to your activity (animation).
3. Vulcan, caverns with their local animals.
4. Beautiful landscapes.
I was sincerely delighted by this Sim and I advise you to visit it.
