This game is great as long as you don't rush through it. Even though you can beat it in about four hours, you have to take time to do some of the little unnecessary things to really like it. (i.e. Keeping Skinner, Shanks, and Cook informed on your investigations via e-mail)
If you're a big fan of the show, you'll love the game too.
