Regarding Naruto Ultimate Ninja storm revolution, I can say that this is the same Storm 3, only the plot was rather invented by the developers themselves, rather than by the mangaka Masashi Kishimoto, this is a kind of addition to Storm 3 rather than a separate game, but the developers apparently decided to release it as a separate game and earn extra money.
I wouldn’t say that it’s not worth it, because during sales it costs a penny, cheaper than any DLS from EA :D In general, the game differs from Storm 3 in that they added many interesting and new heroes that do not exist in the actual the concept of the Naruto manga, such as Mecha-Naruto, and many interesting costumes, the multiplayer has also been improved, it is now more convenient to play, and most importantly, new attack combinations have been added to all the characters, etc.
In general, the game deserves a solid 9 out of 10
