The storyline (without spoiling anything), is very well written. It comes off in a way, as an interactive movie and that's a good thing. I think this is one of the best storyline's in a video game, that there has been in some time. If you're like myself and have no previous knowledge of the history of Sam Fisher, don't worry, the game has flashbacks that'll explain everything you need to know, and a little more. While the flashbacks are cool..
