It feels and plays pretty much like the first game on the PS Vita in all honesty but I am pleased at how much it captures the essense of the Xbox 360 version as I find myself saying "ah, yes, I remember that" as I'm working my way through it (I'm on Chapter 4... or 5). I never played the Sigma version on the PS3 but I'd guess it includes all the extras from that. It also manages to run at a smoother framerate than the 360 version as I haven't noticed any real slowdown. I think there might be fewer enemies (or maybe it's because I'm playing it on Hero difficulty?). IMO, it's a fairly solid port that even includes the extra game modes and costumes plus the visuals look great on the 5" OLED screen. If you enjoyed the first Vita NG game then you will enjoy this one too. Somehow this game just feels more impressive on a handheld; maybe it's just the buzz of playing such a cool game on something other than a big screen.
@Darren Are you finding Ninja Gaiden Sigma Plus 2 pretty much identical to the first game, bar storyline, or are there any other improvements/differences?
I do find the icons a little small and hard to read on the HUD though - the ones accessed from the D-pad - but, fortunately, you can access the pause menu and switch weapons and use items from there.
