NG since it's rebirth on the XBox has always been blood and guts, but the last game the fans felt betrayed because the developers toned down the gameplay so just about anybody could have beaten it. In NG2 the main character regenerates health for crying out loud. Now they are removing other elements which also effects gameplay. For example you're not going be able to cut off legs or arms off enemies which was a great tactic to beating hordes of enemies.
If the series needed tons of blood and guts and a challenge level so obscene few could complete it for the experience to be
entertaining, in my opinion it wasn't a good series to begin with. Considering statistically so few gamers even bother to complete games with manageable difficulty, I fail to understand the logic of choosing to make your game so punishingly hard that even
fewer people will ever experience the full game.
I tried the demo for the first Ninja Gaiden Sigma a while back, and just found the experience frustrating (especially the really terrible camera). If they're taking steps to actually make the game
fun for people like me that don't
like an endless gauntlet of unforgiving Trial & Error hack & slashing, the game's probably better for it.
