Dude Demon's Souls was awesome. 
I really liked Boletaria. it was pretty and ugly at the same time.
The really interesting thing I find is how they used the characters. You learn basically nothing about them, but just enough make you interested. Like Yurt the silent Chief, the guy that goes insane and murders everyone in the nexus.  When Biorr of The Twin Fangs just shows up to help it was awesome! I'd  really love to see the whole story behind Garl Vinland and Maiden Astraea, also that boss fight was really fucking sad.  I thought the voice actting was really great and the gameplay supremely rewarding.
