I played a demo a few years ago, in which you started on a big platform.
Below there were a group of Velociraptor mongoliensis, and if I approached them some guy started talking: "Velociraptor: a small theropod, native to China and Mongolia".
And so on.
The demo ended behind a large gate, and a Tyrannosaurus rex strolled around over there.
Now I don't now what this game is called, so does anyone know?
I liked it.
