Demon souls IS A MUST. Import it in English from Asia. USA release date is fall 2009.
Is the best action RPG this gen in my opinion. Better than Oblivion/fallout3/witcher and sacred 2 combined.
Folklore is also the most hidden gem this generation. The true delight of it is its atmosphere and filosophic and mystical story.
