About 14 years ago, I discovered a gem of a game called Life and Death. It was a doctor sim in which you diagnosed and treated patients. The most exciting and challenging parts of its gameplay were the surgery sections, when you had to perform entire operations - from laying out the sheet and disinfecting the gear all the way through putting the final stitches in the incision. Although I was too young to appreciate the title's finer nuances, I did have a tremendous amount of fun carving my name in the patient's flesh with the scalpel and listening to his resulting screams. I eventually put Life and Death aside and moved on to titles more appropriate to my temperament such as Wolfenstein 3D and Blake Stone.
