This one was my personal favorite.

It expanded on the way the Storm Series was played in innovative ways (Substitution Bar from Generations, fighting multiple people as a bosses at one time, Hero/Legend selection that gives you different cutscenes and boost replayability)

The fact that you start from Minato vs The Masked Man, then the Nine Tails attack is sick. Then you continue through The Five Kage Summit and The Fourth Great Ninja War (which arguably, the game did better than the anime and manga with having a Naruto v Sasuke fight).

Storm 3 might not be the best Storm game in many people's eyes, but it was the best damn one to me. If not, it's at least tied with 2.

The coolest hack n slash game you'll ever play. The amount of badass, over-the-top attacks and combos this game offers is ridiculously fun. You can attack with akimbo rocket launchers, a motorcycle or convertible nun-chucks. The game offers a quick paced, short duration missions which are really entertaining, though the story itself is pretty inexistent for the amount of playtime the game offers, though the story doesn't really matter. You get to play as 3 characters and they have so much depth and personality that it sometimes feel like you're playing 3 different games. Really fun and over-the-top game.
