Magnificent story, which is presented in magnificent way. Graphics, music, and gameplay are important, but they are only servants or greater purpose - to tell the story of madness and how to recover mind from it. Why only 4/5? I think some fighting episodes was too hard - not because of enemies, but because of some camera issues. Also one of bosses is very hard to beat because of flashes on screen. Nethertheless, definately must-buy game.
