Yeah, this game's worth the buy but I want a uh "digital backup", too
I bought the game, pretty worth it IMO. Already enjoying it more than Revo 2.
And yes, the last story mode battle is frustrating as FUCK
The whole rest of the game is easy, but the last fight is HJFDSHFJSDFH it's not even fun.
You're Ninetail Naruto; and it's Deidara with super armor, super damage and he's in Crisis mode, so he's making like 4 clay spiders at once.
When he explodes a bunch of them on command, you'll lose like 3/4 of your life. But if you fought Kabuto at the end of Revo 2 you'll come up with a good strategy.
But don't let that stop you from buying the game, man
Wifi is kinda neat, though I haven't tried it yet.
Despite all the Naruto fanboys, Naruto fighters haven't been half bad. I've played 'em at my friends house and they're decent. Not anything that warrants a download from me, but not a terrible anime game.
