For those who don't know, Ninja Gaiden is a series of games based on the original Ninja Gaiden on the NES. However, renewed interest for the series came up once Ryu, the main character of the game appeared on Dead or Alive. As the series went on they chosen to make a new Ninja Gaiden (plus in my mind to fight with Sega on their ninja year) and as such, being DOA, some of the DOA characters (erm, one) appears as part of the game.
In Ninja Gaiden SIgma 2, your able to play as Ayane, the opposite of Kasumi from the Dead or Alive series. Now, why would this interest you? Because the grab attacks are CRAZY wonderful and it's lovely ryona filled once you get grabbed. Or even attacked. However, the main reason I made this topic is that for those who plan on getting the game because of this, be sure to understand Ayane isn't fully her own game in the game.
In fact, if you mainly want the ryona part of it, play the demo that you can download off the PSN network (dunno if it's in the Marketplace). You can get all your ryona fill from it as it's just great stuff. If you want more though, then you should get the game as it also includes two more characters (both female) to play as, and get killed.
