Pros: Replayabilty, many ways to complete missions, good story line and nice graphics
Cons: no multiplayer

I bought this product because I rented it one night and found it interesting. After I owned it (and the book) it got even better. It's an awesome game because you can finish the levels by being sneaky or by blasting your way through or a combination. The replayability is endless. You get 7 in-game saves per mission, so as you progress through the level you can save it and start there next time. At the end of each level you get rated on how well you did from Silent Assassin to Mass murderer (you get bonuses for Silent Assassin status). The storyline is great, you can easily BECOME Agent 47. As I stated in the subject there are only 4 games that I've ever REALLY liked, Starcraft, Diablo 1 & 2, and now this. Under $20 it's a steal!!!!!!!
P.S. - Find a walkthrough on-line to help get a Silent Assassin rating.
