Don't get me wrong, its a good game. Its just that there are some quirks about it that even the developers have to see.
The fighting is easy, but since they put a timing mechanism in, it can also appeal to hardcore gamers in which skill in a game are recognized as their strong point. The character selection Is Just above satisfying, while the stage selection is lacking. all of the fighters have their own Ninjutsus (Powers) And ultimate Ninjutsus which are Uniques and fun and fair to pull off. Inititiating a Ultimate makes it so that if you fail, Its your own fault, and have nobody to blame. (unless someone smacks the Sixaxis out of your hand).
The Leaf village looks pretty good, but its a ghost town, there are about 48 people on the whole map. and the shading is wonderful but the enviorments could have used a bit of a realistic touch to make the game look at least a little serious. The sound is good aside from the occasional sound glitch when using an Ultimate to win (It sounds like bomb going off in the matrix and glitched).
And while there is DLC (downloadable content) For the game. They are only support characters most of which should have been normal ones, and A couple missions. And the downloads are spaced pretty far apart in regaurd to date. there have been rumors of stages being downloadable for lack thereof. There are unlockables in the game like music and Character models but theres really nothing to make you want to beat the game in the long run, other than getting all the Jutsus and the last cutscene. Its a good game, i think even if you hate naruto you wont find it unbearable.
If you want something to hold you over for a couple months pick it up. You might or might not like this title.
