Glad to hear you, usman.
Oh yes, Heavy Rain is a highly recommended PS3 exclusive that you just can NOT afford to miss! Take my word for it.
Plus, if you have the PlayStation Move and Navigation controller, that will make the game tht much more fun and immersive.
So, do make sure you give it a go. Even if that requires renting the game for cheap.
Just so that you know, Heavy Rain was one reason why I got the PS3, and my decision was justified I realized soon after I played the game.
PS: What other games have you played so far and which ones do you currently own AND which ones are your favourite?
