I played this game on a friend's ds lite. I was a doctor (psychiatrist)who travelled on the staten island ferry to a hospital. In the hospital were 4 or 5 patients who had been admitted for a variety of reasons. They were all kept in separate rooms and I could question each one individually. there was a nurse's station where I discussed the cases with another doctor and nurse. I could travel back ond fore on the ferry to my hotel in New York.
