If I'm channel surfing and see open heart surgery, I immediately need to change the channel because it makes me feel squeamish for some reason.
I wasn't sure if Trauma centre was a game I'd be able to play, but I can tell you it is honestly not like that at all. As others have said, it's not done in an extremely realistic graphic style and I think it actually helped in removing that uneasiness I felt when seeing those type of operations.
Damn fun game too. I sweat like crazy on the harder missions. I'm currently on the final stretch of missions. It's tough, but not unfair, and that's why I keep coming back. Awesome, awesome game.
