The game Eternal Sonata (formerly know as Trusty Bell) from Namco Bandai has an interesting story to say the least. The story takes place in a dream world which centers around the piano composer Frederic Chopin.
The game isn't for everyone, though the graphics are looking pretty good. Japan will be getting it on June 14 this year with the US and European versions soon after. Check out the screens and see if it's for you.
