I think it will be worth it. I have it and am inthe process of finishing it, so I don't know how long it is, but I've perfomed a lot of operations! The graphics, for what they are, are great. They aren't super realistic, but I like them. Even if you have the DS version...which I do...you'll like this one. The way you choose your instruments is so smooth and there's nothing like actually moving your whole arm when doing things like suturing and cutting and taking things out with the forceps....awesome!
If you do it...let me know what you think of it, okay?
Did I mention you get to use your medical instruments to diffuse a bomb?????
