With procedures rarely clearly explained, frustration is quick to take over, and the time limit is just annoying. A normal operation has a time limit of 5 minutes, which doesn't seem so hard until you get stuck randomly away at the screen, trying to figure out what to do next. There are also a few instances where you must perform 3 surgeries back to back within a 10 minute window, only to fail on your last patient because you ran out of time, forcing you have to go back and restart from the very first patient. The controls are the only thing that makes this game truly playable, as they're very forgiving, and feel natural to any DS player allowing you to perform surgeries without many mistakes. Overall, Trauma Center: Under the Knife 2 was very anti-climatic, and one would expect more from a sequel to such a huge hit.
Pros: Easy to pick up and play, controls feel natural
Cons: Gameplay becomes boring quickly, more dialogue than actual game time
