Well, you don't really do anything in this game and its really short. All of the questions for suspects are scripted so you just ask all of the questions and you'll get to the end. You also have to find evidence so you just sweep the crime seen and pick up everything you can, then bring it back to the lab. Greg tells you what to do with it and if you visit Brass and don't get a warrant, you missed something. Go back to every location and sweep for more evidence. Bring it back to Greg at the lab and talk to Brass again. Wash, rinse, repeat until you can get a warrant. Pretty boring game, not even worth a rent in my book.
I had the game for the ds and it was pretty good as far as story lines. The graphics could have been better. It is not as easy as it seems on tv. I hated the fact that you had to complete one step in order to do something else. So I was constantly rechecking my evidence to make sure I did all the steps. Then even sometimes it did not register. Once I got the hang of it the game was not to bad.
