I am a long time fan of the anime but never played any of the previous Dragon Ball video games except for Dragon Ball Z Fighter.
The graphics were awesome. The fighting is classic Dragon Ball fighting style. I love the interaction with the environment (You can knock people through mountains or get pummeled into the ground and leave a crater, fight under water, etc.)
I've seen some of the few negative reviews and I totally disagree. All RPGs are repetitive so I dont understand that complaint. You advance through the main story, do side quests and then advance through the main story. Thats the format of every RPG. Yes, the game follows the anime story line, but that was the intent, not to create a new story arc. To me, I think this will end up being the best selling DBZ video game of the series.
