Timmay from HalfLife-Mods.com has interviewed eot156 from the Jurassic Rage team.

Here's a snippet

Timmay: Will you have a map/level where you will be able to be dinos?

eot156: We are not planning to allow players to play as dinos. Dinosaurs are going to be acting as real as they can be, and if we have some dork controlling a Trex and running around messing up the whole story, well that just would ruin it. Our dinos will be good enough, they are going to be real in the sence that they will smell blood, and be attracted to sounds. This would mean the predators are going to be where the action is at =p.
