Operation was a fun game, but fatally flawed (no pun intended). The sad fact is that no game can hold the adult attention span unless there is a strong possibility of someone getting injured while playing.
That's why Shocking Autopsy is Operation for adults. While you pull various weapons from a gangsters body, just make sure to avoid any mistakes with those tweezers. Otherwise...ZAP! Your turn is over. (Because you're dead). And then whoever bangs your wife first wins.
