The Metal Gear Solid series is famous for the way that Hideo Kojima (the game's creator) orchestrates the narrative, creating a film-like effect.
It has been said by some to be the game's biggest strength, and by others to be the game's biggest weakness (because the cutscenes can go on for ages, when you'd rather be playing).
The games are also famous for having great endings, where everything is resolved, and there is usually a plot twist or two.
As the article suggests, this article is full of Metal Gear Solid 4 spoilers, so if you don't want to know the story and the ending, stop reading now.
