This game is VERY addictive
The graphics are decent. Its pretty much the same graphics for your average psp game. Although they sometimes lag when they start there special move run.
The Sound is simple. Ninjas fight to flutes blazing in the atmosphere.
The Gameplay is the best on the psp. Its fast-paced and very actiony. Plus it is sort of addicting if you ask me.
The playability is very high if you ask me. you will play this almost everyday. And that is a guarentee .
Overall I love this game. It may lack in some cases but its something to play everyday.
