My english not good i can't say much , but you can watch this video which is compare difference between Ninja Gaiden 2 Vs Ninja Gaiden Sigma 2 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rr3d6DPBOHI.htmlsi=eV6aQMkNpA_ViDg1
combat direction in sigma 2 3 great ideas has been added: 1- You could use bow and shurikens together for the first time in the series. When you use the bow in the air then fall down if you hold forward you could get into a running move. And that's a huge combat addition. Especially for flail and talons. 2- Enemies have more health. In vanilla when you use Dual katana or Falcon's talons Enemies die so quick. So in sigma 2 you have more time with the enemies to explore the weapons. 3- flying bird flip in sigma 2 got adjusted. in vanilla your flying bird attack most of the time will miss. Overall Regular 2 is more snappy and more polished than sigma 2. Both games should be played.
The video is the Sigma 2 Black mod, that aims to revert the controversial changes that vanilla Sigma 2 made to make it play closer to the original Xbox 360 while keeping the enchancements that Sigma 2 brought. So best of both worlds but while the mod is playable from start to finish it is still a work in progress.
