Summary
Good Game, Bad Things.
The Good
It's Dragon Ball GT!! It has GT characters! It's in 3-D. It's a game like no other. The opening animation sequence is awesome. The character taunts makes this game 1 of a kind. Not to mention the Meteo system! Fast flying punches going right at you!
The Bad
The slow gameplay is the one thing I think most people hate about this game. For me, it's their voices in English. It sounds very bad! Not to mention all those characters. 6 Goku's? 3 Trunks'? They all have very similar techniques and similar button hitting to do a move. And when they fly, it's just them standing the way they would on the ground but in the air. They also stopped making this game. Why?!?!
The Bottom Line
It's a decent fighting game. Just like a normal fighting game with DBZ/GT characters in it. Go ahead and search for it on the Net, get the Japanese version for the real Japanese voices and get the English for collecting.
