I found this game to be very enjoyable.
The story line is very linear but don't let that put you off, your here to be a surgeon...
It starts of nice & simple with procedures that guide you through the tools to use, it will not allow you to use anything that is not needed at first while it's teaching you the ropes.
Later in the game all surgical equipment will be available to you as you become an accomplished Doctor.
This game has replay value as after each operation you are given a ranking, you will find yourself going back to try & perfect it, you will be rewarded with a better ranking.
On top of this you can play the game in 3 modes, Easy, Normal & Hard, each has its own ranking system so even more reply value.
Average rating on this game is about 8 out of 10, I'd personally give it 8.5, I'm sure you will agree.
