Demon's Souls VS Heavy Rain

[Nirvana_Nut85]

So I was in futureshop today and I decided I'd buy a new PS3 game. Pretty much what it came down to was either Demon's Souls or Heavy Rain. I literally debated for about 45 minutes over it and I decided to go with Demon's Souls ( it also is only $29.99 which helped a bit) . Now I haven't opened the game yet so I can still return it but did I make the right choice? Or should I return it and get Heavy Rain? If some of you who have played both games could give some input it would be helpful as I am second guessing my decision.
