The GP review did pretty much nail it, it is certainly a step in the right direction but is missing some key elements. Namely the combat system which is a bit shallow and underdeveloped not to mention the annoying and inevitable "punching the air" with your back to your opponent, which seems to happen a lot in this game. The targeting system is also very annoying, rather than clicking the RB button and being able to cycle through your opponents, the targeting system seems to pick for you at times depending on who is closest or which opponent comes within camera view - this is frustrating because often times you need and want to finish off a certain opponent first. Also, the manner in which dragon balls are collected is another tiring grinding bore. What makes this game ultimately fail is that it is a grinder game predominately, it asks you to play the same levels over and over and over again and again and again in order to gain EXP or acquire the item you want, this is just poor game mechanics in general.
It does become monotonous but leveling up your character and the ability to change his clothes/accessories helps keep the gamer involved and excited in the game, but as far as progression in the game goes, the fighting system is just too shallow to allow for some real fun and difference/strategy between battles.
A step in the right direction indeed it is, but still lacking the luster we were all hoping for, at this stage of DBZ games you would think small final finishing touches would be all that is necessary in the games, but here we are, STILL needing some major mechanic overhauling and game direction done. It is a sad state of affairs.
