Does anyone know any good and deep dinosaur games out there?
I'm chiefly looking for something where you are outdoors (jungles, for instance) and where you always have to be on your guard.
The closest I have come to this is Trespasser and that game was decent I guess, but it felt a bit, I don't know... lifeless.
I love the feeling when you walk around in beautiful environments and always have a feeling that something is behind you, and it would be even more exciting with dinosaurs.

It's also a plus if the game has a more general focus on dinosaurs, not just on the rather trite T-rex/Velociraptor/Triceratops pack.
Those dinosaurs are certainly cool, but they are a bit too common.
