||One of the best games for Xbox is appearing in full form on PlayStation 3! Be assured, Sigma is the definitive version of Ninja Gaiden...Whenever Ninja Gaiden is talked about among reviewers, it's most often touted as one of the greatest games of all time; a modern classic. While I don't think Ninja Gaiden as brilliant as it's considered, and I still prefer God of War for my action gaming, it can most definitely be said that I have thoroughly enjoyed and been impressed by Ninja Gaiden Sigma...Sigma is an odd animal: it is neither an expansion pack, nor is it a straight port. Rather, it's more of an updating of the game. The visuals are obviously the first new content you'll notice and yes, they are breathtaking (most of the time); particularly the animations are entirely stunning. Sigma's core gameplay has a poetic fluidity that almost demands the new visuals and animations. In fact, I can hardly fathom going back and playing the Xbox original...I think this is pretty much a no-brainer if you own a PS3. If you haven't played the game yet, then all the better. This is the best version by a landslide. Yes, there are problems with the game, and yes, they don't get talked about enough, but the core gameplay is just so amazing, you might not even notice them.
