Well, I played both the original Ninja Gaiden, and I loved it, then came Ninja Gaiden Black, and is very good. I'm currently playing it at Very Hard difficulty, and its tons of fun. When I heard that Ninja Gaiden Sigma was coming out, i looked it up and found out that its for the Playstation 3 ONLY
which made me angry. Like come on the other two games have been on the xbox, why not the third one? I guess the PS3 really needs good games. But anyways MGS will feature Rachel, the heroine from the two previous NG games as a playable characters, along with new weapons and costumes for Ryu, the main character, enemies and bosses. I look forward to playing it at my cousin's house.
