I had to edit because I forgot about Castlevania and I took Heavy Rain off that list because I honestly wasn't blown away by the games graphics, great facial animations but didn't dig the scenary. Also while play each game mentioned I had a oh fuck moment in my head while gazing at the graphics so thats what I based my list off. Also Alpha Protocol and NIer are worth mentioning. Best Playstation 2 graphics ever lol.
