Note that this is the 3rd time I have bought Ninja Gaiden: bought Ninja Gaiden when it was first released, and then again for Ninja Gaiden Black (Still have not beaten it, I got to a rolling rock puzzle in Black and then lost interest for some reason, I think it was We Love Katamari).
Anywho, this is actually a very interesting port/remake, to say the least. Some areas feel like straight ports of the Xbox version, while others feel like they have been completely retextured and had the shaders modified quite a bit. Currently, I am on the airship.
Anywho, the game feels a lot like a "directors cut" sort of feel, more so then Ninja Gaiden Black. One example is near the end of the Hayabusa Village chapter, where the black samurai on the horse is now on fire. Not only that, but you now have a small new area in the burning village section where you actually fight Doku instead of see it in a cutscene (Also, they changed the CGI sequence to a real time cutscene). Thats was very awesome, and something they should do more with ports of older games.
The bad part is the cut content...Not everything from Ninja Gaiden or NGB is in this version (The older Ninja Gaiden games, apperantly some enemies and costumes are also gone). I also noticed that the rod you get in NGB is no longer in the village, or at least I didn't find it. Also, the draw distance is sort of odd sometimes: some areas are much darker on purpose (Such as where you fight the black Samurai, but that may have been since he was on fire) and you cannot see as much in the distance sometimes. Also, the FMV sequences that are still in the game are pretty ugly in widescreen.
Reguardless, there are small other changes they have made as well. While it isn't quite "complete", it does feel like the true version of Ninja Gaiden. Even though the price is a bit steep for a game that can be bought from anywhere from $9-20 bucks, PS3 owners may want to check it out (Since, lets face it, there is nothing else coming out anytime soon....)
