For me, it's everything about Norman
 
1. Threatening Blake for beating Ethan's psychiatrist.
2. Chasing a criminal through a supermarket.
3. Saving Ethan from Blake by pushing him to a wall and punching him to the face.
4. Fighting Mad Jack.
5. Fighting Scott Shelby in the last chapter.

For me it was the first time I used the virtual office in ARI, I had no idea what it was, picked the one that looked like Mars... it just blew me away!

The moment when I realised who the killer was. OH SNAP!

Playing as Madison, I accepted the drink from that dude, which lead to some... interesting events. Thinking about them now, they're super contrived and don't make a whole lot of sense, but in the heat of the moment, it was just the white-knuckled terror of "OH GOD I'M TOTALLY GONNA DIE HERE." I remember coming away from that sequence thinking "Man, that may not have been the smartest choice, but I'm glad I made it because that was awesome."

Yeah when I realised who the killer was and....

Also, another thing I appreciate about this game: You know in most games, you're shooting all the time? In Heavy Rain, when someone pulls a gun, you KNOW shit's going down. In Heavy Rain, guns are to be feared and respected, unlike other games where they're just utilities.

I just beat the game and I was kind of hoping he would get back to together with his wife. They really made you care about the Mars family in the beginning and I was hoping that they would all be a family again at the end. BTW, Jason dieing in the beginning was probably one of the saddest moments in a game. Overall this game was pretty awesome and I can't wait to see what Quantic Dream does next.

The entire Shark trial scene had my blood pumping like crazy. The moment in which I made the decision to either shoot the guy or not seemed to take hours.
 
"I'm a father too."
