Ninja Gaiden 2 

Awesome game where you go around killing ninjas, dragons and fiends with ninja weapons and fireballs (there are actually several different types of "ninpo"). It is the sequel to Ninja Gaiden for the Xbox (obviously), and you play as Ryu Hayabusa. It is also insanely hard and will require a lot of skill and patience, especially on Path of the Master Ninja, or even Path of the Mentor.

<MasterNinja2983> ...Ninja Gaiden 2 takes a lot of skill. It's a good game, maybe you just need more practice.

<BLIZZARDRULZ11216> NO, IT'S PHYSICALLY IMPOSSIBLE!

Gaiden 

A side story or a spinoff of of a published work. It is not considered as a prequel or a sequel. Some gaidens are just stories retold from another character's perspective, or a flashback.

In a gaiden of Dragon Knights, by Mineko Ohkami, Rune has a nightmare of everyone becoming crossdressers.

Ninja Gaiden Black

The video game equivalent of natural selection.

If you're one of those whiny adolescent morons who threatens complete strangers with violence over Xbox Live despite the fact you haven't even got hairs on your chin, don't play Ninja Gaiden Black. The sudden jolt back to reality may annihilate you.
