The Greatest Psycho thriller game you'll ever play.
I was impressed with the story; Unlike Fahrenheit it's much more interesting and along with its realistic theme it's easier to get along. Cracking the game's story ain't easy, you really have to put your head in the game order to understand it, Decision makings in the story will leave you mind dazzled, taking you parts unknown (It means your decisions will take you to a specific state or a possible breakthrough) . Actually depending if you really care much about the storyline, The more 'correct' decision you make, makes the plot more easier and same as if you take "incorrect" or stupid decision you may find yourself some wasted time or harder plots to crack.
I find it somehow funny but Heavy Rain is also an exercise, the game's control will make your hands and arms more active and if you play intense you may find yourself "jumping" as the game goes on. As many people said one cool thing about Heavy Rain is the character emotions, well I agree about that but it's not really the big thing in Heavy rain, It's the Plot or Storyline I'm referring to. Without the storyline the character emotions would have been useless.
So to finalize it after hours of playing Heavy Rain I'd rate it 10/10.
Well this is all I have to say about this game. So See you around.
