god of war is amazing, the story line destroys the other two's. Also the gameplay goes to god of war as well, even though its a hack and slash type of game, its an amazing hack and slash game.
devil may cry- the series is great not as good as god of war, but great non the less.
ninja gaiden- its to hard, and gets repetative sometimes, but its still a great game nearly as good as devil may cry.
