I played all the other ones on XBOX and 360, been a die hard fan since NES days, beaten them on hard difficulties, yada yada yada. Borrowing my friends PS3 and playing Sigma (which was perfect) and Sigma 2. Sigma 2 is kind of a FAIL. They made it way too easy, made the Muramasa shop essentially useless, the music is not the same, took the blood out, the list goes on and it's obvious this was a middle finger to Itagaki IMO. Had I played this when it came out I would have seen NG3 and the disaster that turned out to be coming. NG3: Razor's Edge was fine, hopefully they learned and NG4 will be what it should but we'll see.
