I'm not a Dragon Ball (Z) fan, but even I highly enjoyed this highly addicting fighter! Must-buy at 20$ price!
So, when you start Dragon History, the story of the game, you gotta pick a Saga. Beat that saga, move on to the next and beat all Saga. A Saga is a series of fights you go through. A fight is a Duel. Dueling is the main gameplay part of the game. You & a friend (or Computer) will be a character, enter a huge arena and duke it out.
Now the Controls are great, ONCE you get use to 'em. You can use the GCN Controller, the Classic Controller or the Wiimote/Nunchuk. I, unfortunately, do not own (nor do I plan to own) a Classic Controller, so I can only talk about the GCN/Wiimote-Nunchuk. I believe both of them are great.
Now, the battle system. I love how the arena's you'll duke it out in are so large. Its fun to just roam around them, and how you can destroy some of the environment. But when it comes to the battle, the goal is to of course, deplete your opponent's HP. In Team Battle, you must deplete the HP of your opponent, then deplete that of the next opponent & so on.
There also lots of unlockable Stages & Characters
This game is so much fun. Great Graphics, Great Controls, Fun addictive gameplay, A pretty good story (from the perspective of a non-DB(Z) fan), a low price tag, terrific voice acting (again from my perspective) and fun Team Battle.
The only downsides I found were that one, the Controls can be quite tricky if you doun't know how to use them, two, the Online Mode has HORRIBLE LAG (which is dissappointing since it's so much fun), three Dragon History is a little on the short side.
But this is still a great game that is worth a BUY at its 20$ price tag.
