This is one if the hardest but best DBZ games i have played.
Some of the battles are espically hard to get threw.That is not all bad though. It does give you a really good challenge. Unlike previuos DBZ games you have to use more startagy then just shooting energy attack like clazy. I found the surving battles in Z battle Gate to be a pain.
Two of the big draw backs in this game are the crappy voices while in battle, and that the Z battle gate doesn't really follow the story line. I will give an example. In the Future Super Warrior gate the last match is Future Trunks Vs Gogeta. As any DBZ fan can tell you Future Trunks never fights Gogeta in any of the story lines.
Other then the very few problems with this game It is a really intense game and I really loved playing it. So if you like DBZ and a challanging game that will push you temper the i suggest you go out the an buy it. If you like easy games that you can just fly right threw go get something else.
