This game simulates a work of a paleontologist, which is not much exciting job, therefore this is not much exciting game. You just dig stones from the ground, drive around with badly controlled cars and clean and assemble bones. You'll get bored even before you complete your first dinosaur.
Plus, the game still looks like early access, user interface is confusing, and game is badly optimized (runs constantly around 10-20FPS even though technically looks like Half Life 2)
