Trauma Center: Under the Knife is a surgical simulation game for the DS. When looking at this games, you really see that this game fits the DS perfectly. In the game, you only use the stylus to perform operations that feel to have light puzzle mechanics to them. The game ranges from an assortment of situations, and gets harder as you go through the game. The thing is, this game gets Really Hard Really Fast. The difficulty gets high so fast that difference between fun and mass frustration clash. This is the kind of game, where it's best to play just a few operations, and then take a break, because it will otherwise be a frustrating experience. If you are looking for something very unique and innovative for your DS, and you think you can accept the challenge, then I suggest you check out this game. If you are a gamer that is not patient and has never been able to beat a game like Super Mario Bros. all the way through:), should probably stay clear.
