Ninja gaiden. Tough, nice, with plot and ever challenging
Ninja gaiden shows a kickas ninja who tries to defend the worl from an ancient ship of doom.
The game is a solid platformer. You have yout trusty sword and with several items to throw, you embark to stop the world conquer.
At the end of each stage, you have a small cinema display, which explains what the hell is happening. The idea of having story well planned is nice, and having a real story is 10 times better.
