Surgeon Simulator, if I were to sum it up, is 20 minutes of hilarious insanity, followed by a few hours of frustration, mixed with the occasional, satisfying, successful procedures.
Surgeon Simulator is packed with hilarious moments of utter chaos and insanity, such as performing dental surgery with a hatchet, bonesaw, and pencil, or trying to figure out the hilariously awkward controls to perform simple tasks like picking up your phone, or putting a floppy disk in a computer. You have probably seen all that on You Tube.
But after about 20 minutes (varies from person to person), but the chaos gets old really quickly. And then comes the frustration.
You'll be trying to actually finish a surgery, only to be constantly pestered by your character's inability to perform simple tasks, such as picking up items, cramming his hand into tight places, putting more than 20 centimeters between his hand and the patient, inability to peek around his arm, and last but not least his spontanious fits of cerebral palsy.
Which is to say that sometimes your character will fail to pick up items despite his hand being straight on top of them when you flex the fingers, the reach of your arm is so short you cannot reach the farthest edges of the operating table, and in surgeries where the patient is upright, you can barely get your hand over your patient's head, making it nigh impossible to avoid smacking your patient in the face with whatever you're wielding. Besides that, your arm will almost constantly be blocking the view of either your tool or the organ you're trying to sever, and you will constantly drop things despite having a firm grip on them.
These arduous controls are what make the game fun for the first twenty minutes of intentional chaos and carnage, but are also what makes the rest of the game time horrible, and filled with unintentional chaos and carnage.
It does have plenty of good humor, though. I particullalartly liked the TF2 easter egg.
I have decided not to recommend it, but this is only because I would not recommend it at its normal price. I bought it during a sale, and that is probably the primary reason I am not overly disappointed with the game.
If you like chaos and mayhem and randomness, then you'll probably have a good time. If you like to get stuff done, then this is really, really not the game for you.
