Are Ninja Gaiden Sigma 2 and Ninja Gaiden 2 exactly the same game?!

I just got Ninja Gaiden Sigma 2 for my ps3, and it looks almost like exact same game as 360s Ninja Gaiden 2?! What the heck!

They are the same game story wise but the PS3 version has alot of extra features.

PS3 version has

• New cutscenes and areas
• 4 playable characters
• Co-op mode
• no blood
• Smoother gameplay

So yes it is the same game, but with new things. Sigma 2 once you get into it is the better version hands down.
