• Video games based on hunting themes have been somewhat controversial, with animal activists perceiving such games as encouragement to shoot innocent creatures. Hunting games with a prehistoric theme avoid this sort of backlash and allow people to unleash their predatory instincts in a harmless manner.
  
  

Carnivore: Dinosaur Hunter

• An iPhone download, Carnivore: Dinosaur Hunter begins with easier challenges that take on herbivores and works up to the most ferocious predators as your score climbs. The game scores based not only on kills, but also the methods you use to hunt your prey. Finishing off a dinosaur with the help of a tranquilizer will get you more points than slaying it outright. And if you use aids such as disguised scent and radar tracking, your score will decline.
  
  A review of the game at PocketGamer.co.uk says, "Those of you that lack patience may find it a bit demanding as tirelessly tracking the larger targets is often a drawn-out exercise in biding your time, but the sense of reward when you eventually take down a slavering T-Rex is incredible."
  
  

Jurassic Park

• Jurassic Park, a mobile game adaptation from Gameloft, is based on the two protagonists being hunted by dinosaurs as they try to flee an island after crashing there. According to a review of the game by PocketGamer.co.uk, "The general gameplay is entertaining enough to keep interest high---great animations and tight controls allow for some fun, cover-based shoot outs and life-or-death chases against the lumbering T-Rex." The game, however, is "extremely linear," the review notes, "with arrows always pointing to the next impressive set-piece and very few points from which to improvise."
