Being that the PS3 is my first Playstation system (grew up with Nintendo), I really only felt comfortable with Nariko. The first exclusives that I owned for the PS3 happened to be Warhawk, Heavenly Sword, Folklore, Lair, and Valkyria Chronicles.
I already knew I was gonna get this game (wanted another fighter to get away from Marvel 3), but I also knew if anyone from those games mentioned made the cut for the roster...I was gonna gravitate toward them.
So, Nariko it was. And Nariko it still is.
