Pros: good combat system,great flow.
Cons: does not appeal much in visuals category.
The bottom line: overall a good game.
I would certainly buy it because i like the earlier games.
players must work their way through 19 chapters, dissecting enemies with an array of razor-sharp Oriental weaponry. If any single element of the first Ninja Gaiden defined the title's success, it was the combat system.Additions include a selection of new weapons, with the double-bladed pair of short swords being the most useful. There are also apparent improvements to the AI of the enemies, who do seem to coordinate their attacks with a little more forethought. A smattering of new foes are thrown in too, though they bring little more to the game than the smallest aesthetic variations.
This fluid control scheme returns, letting you turn Ryu into a whirling windmill of gleaming steel and slicing blades that springs about the screen, leaping on enemy heads and somersaulting off walls, unleashing lethal combos and reams of blood in equal measure as swords cut through flesh like hot knives through butter.
The biggest, and perhaps most surprising disappointment in Sigma is the game's visuals. While the graphics are by no means bad, by next-gen standards they are decidedly average, and occasionally disrupted by tearing, jagged edges and miss matched collision between bloodstains and walls. Here Sigma is a victim of its for bearer's success. The original was so outstanding by previous standards that, relatively, more was expected from the new Sony powerhouse.
overall a good game but there are better games out there.
i would give it a 7.5/10.
