There's so many good games on PS2 - but one for me that stands out for originality, story and format is called Fahrenheit (in the US it's called Indigo Prophecy). I won't go into too much detail but the way the story develops hinges on your decision making. Some of the combat / action is a little repetitive but it's well worth a look if you fancy something different. The story is compelling and the fact you play as different characters throughout the game is interesting.
