I think it needs very big changes in my opinion , to look different from its predecessor. Thing that Storm 3 clearly failed to do as we got 1 less combo .......... and an L1 R1 move which is cool , i like that but you can't just remove stuff from the game.....
1-EVERYONE gets a new and balanced moveset to be on par with the others. An example of why this is needed is Jiraiya , imagine he is your favourite character and you would like to play with him , he is just too damn slow to keep up with the others so are some other characters. If you try Kisame you will definetly notice that he is faster than it was on generations and he is as good as the others now.
2-Characters that are in the story mode are also playable, there are not "story mode only characters".
3-As many new characters as possible , we fans love it.
4- Legit Awakenings ,not only that kind of blue aura they have . I mean characters like Tsunade have the byakugou still they haven't changed at all .
5-Legit DLC content- Could be new characters , new costumes but legit ones. What do i mean with legit ones? the ones we have seen in the show. For example : Akatsuki cloak Jugo,Karin, Suigetsu ,Kisame without his cloak, Sage mode Naruto with his normal costume etc etc etc
6-New moveset while in awakening mode also a different ultimate jutsu like in Storm 1 . I mean its disappointing when you transform and your moveset doesn't change at all .Imagine you play with Lee and you transform .... your moveset is still the same and that is ridiculous , even PTS Lee moveset changes LOL just LOL.
People say the game is good , it sure is , because its basically like previous one and that makes it good. But in comparasion Storm 3 Does not have much new that's why i dislike it.
