It depends how good a gamer you judge yourself.
For a casual gamer Ninja Gaiden Sigma can be VERY punishing ( I died 718 times on my first play through, now I am ranked in the top 100 worldwide for mission mode though...)
PS3-Xbox360 gap : 1.5 millions and going up in PS3 favor !
PS3-Wii gap : 20 millions and going down !
