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.
While CSI: Dark Motives seems to get less than stellar reviews, it actually isn't quite bad. Gives me the same nostalgia as the Law & Order game for PCs. While it is slow paced, it's a type of sim game, and therefore doesn't hold the requirements for a quick pace. It is interesting, easy to navigate, and very laid back, which makes it an excellent pick for that last game for the night. I would recommend CSI: Dark Motives to anyone who likes to mysteries and solving them. My best guess is this might be a game for older gamers (eg CSI fans and persons above 20 years of age.)
