In my opinion is a PS3 must have title if you like games like devil may cry
Graphics in game are just ok. The game sports some good HDR effects and decent self-shadowing, however, some textures look very last gen, except they are obviously in higher resolution, some models have higher polygon count but don´t expect to see a radical improvement. If you compared the original Ninja Gaiden with this one, imagine this is the PC version, runs in higher resolution (1920 x 1080), much better frame rate (solid 60 fps) and add amazingly fluid animations and some great goodies such as new playable character Rachel (aww man she´s hot!). Sound has also being improved a little bit since it now supports LPCM 5.1 (uncompressed sound), unlike the disgusting Xbox audio quality, which was also 5.1 but believe when I say original Xbox Surround sound was very limited in quality terms, especially with those back surround speakers.
Best Ninja Gaiden Sigma feature is gameplay, period. Nothing comes close if you like action-platform games. Action is just fast furious, blasting, great, phenomenal, incredible, amazing, something worth to remember, you get it? just don't show it to your grand parents because it gets very¨carismatic¨ when decapiting enemies with a huge war hammer (rachel) or Katana (Ryu), believe me this game features some pretty unnecesary violent animations, yet stunning ones (amazing huh?).
This game reminds me the good days of Snes and Genesis. Game is long, 19 chapters, you will have great fun, great satisfaction every time you beat a boss, it's addicting.. I don't have words to describe how classic the gameplay feels in spite of being revolutionary. Perhaps it's all about gameplay quality rather than just featuring flashy graphics.
Some people are complaining right now about game difficulty, I´m playing right now chapter 14 or 15 don't remember.... but the thing is, it sure takes a while to master the moves, to experiment with them, to try to be creative, and the game is almost average. PSN demo is a bit intimidating, yes, especially because of the boss, but believe when I say I would consider it almost a bluff. The game also seems to be very middle-age oriented, but it´s nothing like that, it´s a combination of modern weoponry and middle age, ninjas and demons ala devil may cry. However, play the game first, I don't want angry people blaming me, remember it's just my opinion what you are reading, I don't decide for you, I'm not your baby sitter.
Ninja Gaiden Sigma features loads of combos and they are much more detailed as well as animations, most puzzles are not very difficult but are great, devil may cry is good, but this game takes action games to a whole new level. BUT it´s not perfect, it has some camera issues, not that bad, but sometimes they affect gameplay, particularly when trying to jump from wall to wall (yes Ryu behaves pretty much like old Ninja legends)
Enemies variety will not dissapoint. The main character (Ryu) features loads of movements (yeah some of them are very flashy such as running on walls), never seen something like this in my whole life, consider there are different weapons, each (one or two are the same thing) gives you a different battle style.
Game deserves to be played and moreover to try to understand what the game is really about. It´s really a shame Ninja Gaiden 2 is a Xbox 360 exclusive, if tecmo doesn't realease this game on PS3 later will loose my respect.
