The Turok: Evolution is an interesting creature. It's story alone chews away at a person's suspension of disbelief—a Native American and a confederate get sucked into an alternate dimension, where dinosaurs have the upper hand on technology and territory. This is probably what would have happened had Mark Twain and Sir Arthur Conan Doyle ever collaborated on a novel. Considering the story only has to go as far a setting a premise for the gamer to blow the heads off dinosaur-men, making complete sense doesn't really matter all that much.
