When Naruto Generations was announced and I saw the previews featuring some of my favorite characters and cool cutscenes, it was definitely something I was looking forward to.
I was even more impressed by the fact that in Generations they seemingly tried to address some problems in Naruto Shippuden Storms 2: online substitution spamming and the near uselessness of combo attacks for example.
Combo attacks (taijutsu to the fans) are now a much more significant piece of the action mainly because substitutions are now limited by a substitution bar, though they are easy to pull off.
However, this change is undermined by the simple fact that chakra dashing can be done at virtually anytime, meaning that even should you substitute, your opponent can chakra dash just as fast to your new location and continue his/her assault. A chakra dashing opponent can whittle down your Substitution bar in an instant, leaving you open to incredible amounts of damage. It takes getting use to and you'll usually find yourself either very pleased or very aggrivated, depending on whether you're the one with the empty Substitution bar.
The characters feel particularly unbalanced unfortunately. Several, like Danzo, Masked Man, Kisame, and oddly enough Part 1 Tenten as well, are so over-powered that you'll be running into those handful of characters a majority of the time online.
All the item collection is fun and the Story mode cuts out the QTE's and exploration found in Storm 2 and though I found Storm 2's QTE's to be a negligable experience, taking out the exploration completely does make the game feel a bit lacking.
Of course, both those things were replaced by fully animated cut scenes before and after every 'Tale' and all of them are pretty amazing.
It is worth mentioning though that during almost all the 'Tales', the story progresses just through screenshots from the anime and a few contain fights that seem tacked on just to give the story a few extra fights.
Lastly, there's no music from the show in this game at all, which I think might just be a 'thing' with the Storm games. All the music is just low quality generic music.
All in all, this is a fun albiet very flawed experience.
It's a blast to see and use so many of your favorite characters, to see some anime scenes not in the show or manga, to have plenty of things to unlock and utilize, an online mode that has tournaments and such, but the fun is reined in by unbalanced combat and characters and the tedium of nearly every online fight being against the same few over powered characters.
