my favorite of the trilogy by far. It has some 'dull' gameplay sections of walking around and doing nothing but the atmosphere is so great I don't really mind it. It nailed the theme of addiction, depression, anxiety and overcoming it while not having any weak pretensions of morality. Loved it.
I also really like the arcade mode even if the scoring system might be a little too simple to make it deep.
mp3 > mp1 > mp2 (they are all great)
