Trauma Center: Second Opinion is NOT a quick-and-dirty port of the DS title "Trauma Center: Under the Knife." It has new graphics and animation; new surgical implements and operation types; a second playable character with new missions; multiple difficulty modes; and a revised control system that takes full advantage of the Wii Remote. It's a remake (or "Wii-make," if you prefer) with gobs of added content. As with Under the Knife, the voice acting in Second Opinion is presented in the operation scenes to enhance the drama and punctuate the action.
