[quote name='BigPoeticCanine']How does this compare to the last one? I fell out of love with Naruto recently, but I might be persuaded to buy this one for the right price. Also, I know that the story mode is definitely better, but particularly I'm interested in if its just a roster update.[/QUOTE]
Some tweaks, like when you finish an opponent with an ultimate jutsu, you get a cutscene, ring-outs in certain stages, new fighting strategies with the new feature of "instant awakening mode", but overall the same shit.
The new characters will have unique movesets, but everyone else has the same ultimate jutsu and moveset. Some of the new characters, like Edo Itachi, will have the same moveset as regular itachi but different ultimate jutsu and jutsu.
