And here's the Famitsu review translated from "Kiyoka" on gamefaqs.
Main summary of the game: over 25 characters to choose from, using cards to make your characters stronger in battle, up to 4 playes WiFi to battle each other.
Reviewer Francis Hayashi - 8
This game, because of WiFi connection, a rich selection of game modes, a good storyline. The battles are messy, but its not too bad for character balance. It is very good to use Super moves by just a tap of the screen, which is a very good design.
Reviewer Amanossan - 8
The main con about this game is, because the super move can be used by just tapping the screen, it is extremely friendly for new and old players, however, because this is on a portable, I think it doesnt suit the portable system, its too hard to play a fighting game on a portable system. However saying that, there are alot of characters and modes.
Reviewer Fukami Sandan - 7
As the other reviewers, this game really shines on how friendly this game is for new players. However my complaint is, there is too much unbalance in the characters, some you know are strong, are really powerful, where vice versa. Also, the story modes of the other characters seem to be rushed, so its a bit of a disappointment. However, if you are playing this WiFi, this is a great pick.
Reviewer Keiji Kawashima - 8
Alot of the characters in this game show great similarity in the manga, As mentioned before, its good for new players in the fighting genre. HOWEVER, to me, this game feels more like an action game than a fighting game
It sounds like a winner to me. Hopefully the online will be lag free. Can't wait to get it.
