The operations in this game are awesome. After the first few operations help you and explain what all the tools and equipment does, you have goals and pretty much have free reign over what tools you use which is great because you have to think and it's actually quite challenging which keeps interest. The operations are also very varied which is good and within each game slot there is the opportunity to perform each operation in easy, normal and hard modes which is good for a bit more of a challenge.
However, in my opinion there is too much context and storyline in this game. Although it is nice to have some context of how the people got injured, the amount on this game is excessive so it's a case of pressing select and letting it scroll through it all which is a bit tedious.
But the operations more than make up for it and once you've gone through the context on one difficulty level, you can skip straight to the operations.
Awesome game. Enough variety to keep attention and be fun. Definitely a great Christmas presents for all ages.
