Trauma Center is probaly one of the best games your ever going to play on the Wii.
You take on the role of a young new surgeon learning the ropes. The game follows his (your) progress from being a rookie surgeon to an experienced specialist surgeon with some plot twists along the way.
The story is told through cut scenes with pictures of the characters and text coming up showing what they are saying. Sometimes these can get a little boring and monotomous, all you really want to do is get to the surgery! But as a method of telling the story, they work quite well, you are able to skip through them quickly unlike in other games.
Operations are performed with the nunchuck and wiimote. The nunchuck control stick is used to select tools, and actions, such as stitching or cutting, are performed with the wiimote. When the pressure is on, it can sometimes be irritating trying to select the right tool quickly with the nunchuck stick but for the most part it's not too bad.
Using the wiimote to perform different actions during an operation is fun, you actually feel like a surgeon! Plus, being able to understand medical language is cool (even if some of the words are a little bit wrong!) Graphics are simple, non gory, although some of the language and plot may be difficult for younger gamers to understand.
You have a large amount of control during the operations, being able to really choose whether a patient lives or dies. As well as performing the operations, you really need to keep an eye on the patients vitals (heart and breathing rate). The assisting nurse tends not to warn you until it's nearly too late which can be annoying, especially if you were close to the end of a complex operation.
The game saves after each operation which means that if you do make a mistake during an operation, you don't lose too much. This is important the further through the game you get as the operations do become more challenging (and frustrating at times) and you may have to attempt them more than once.
Overall, I would say that this game is good fun. It feels educational, even if it's not, and it takes advantage of the motion sensitive Wii controls. It can be challenging at times, but all good games should be. Potential surgeons, apply here.
