Heavy Rain is phenomenal, definitely check it out. Valkyrie Chronicles is an AWESOME game as well, that not many people have played. It's a RTS/RPG hybrid and a ton of fun. Don't let the art design put you off!

And don't forget the PSN games! A lot of them are a ton of fun, especially Pixeljunk Shooter, Pixeljunk Monsters, Pixeljunk Eden, Critter Crunch, Flower, SHATTER, Super Stardust HD, and Wipeout HD are all top notch.

I personally hated Demon's Souls. It's definitely a difficult game, but unnecessarily so; a lot of the difficulty comes down to bad game design. It's unacceptable not to be able to save mid level or some sort of checkpoint system. I hate back tracking through levels, which really turned me off about that game.

To reiterate a few suggestions earlier; God of War 3, Uncharted Series, Little Big Planet, Infamous, Killzone 2.

And once you get Blu-Ray movies, you'll never go back again.
