Consider this game about a 6/10. Add a point if you are a fan of point-and-click games, especially those made by Telltale (as am I), and add another point if you are a fan of the Jurassic Park intellectual property (as am I).
The game takes place during and immediately after the events of the first film, and mostly follows Jurassic Park chief veterinarian Gerry Harding as he attempts to make his way off of Isla Nublar with his daughter. The plot thickens as a corporate espionage scheme to recover Dennis Nedry's stolen dinosaur embryos goes awry, and the few stranded survivors left on the island find themselves hunted by a previously unknown species of dinosaur.
As far as plots go, it's one of the better ones you'll see in a movie tie-in. Dialogue is surprisingly natural, and the game reuses a lot of hallmark music and sound effects from the films. None of the films' main characters are featured in the game, but fans of the movies and books will appreciate how "Jurassic Parky" the game feels as it tells its story.
Jurassic Park: The Game by Telltale Games is an enjoyable experience, but it suffers from quite a few technical glitches and just generally isn't as polished or deep as the company's subsequent masterpiece, the Walking Dead series. Character voices tend to have a strange echo to them, more noticeable during quieter moments than during action scenes. Occasionally, going to the main menu will cause your in-game mouse pointer to disappear, necessitating a reload from the last checkpoint. Conversations with other characters are okay, but rarely do your choices of what to say have any real impact. These problems are minor, but numerous.
As this is a highly linear, character-driven game, there are long story segments with little to no real gameplay; if you enjoy point-and-click games you'll know what to expect, but it may be a bit slow-paced for unaccustomed gamers. Quick-time events are sometimes a bit flat, but the good ones are quite thrilling: you'll be hunted by velociraptors, chased by tyrannosaurus rex, and even stalked by a giant underwater mosasaur.
If you are an avid pointer-and-clicker, and especially if you're a fan of Telltale, consider this game. If you like Jurassic Park, definitely consider this game. Don't pay full price for it, but give it a chance.
