If you're a Dragon Ball old school game fan, then you cant let this pass!
Its a "wish and do" game, making everything you want to do, possible!
The only bad thing apart lacking 3 or 4 characters are the techniques, very similar between Saiyan characters. But this does'nt affect gameplay.
Multiplayer is specially fun, and the story gives you some alternative futures, like the possible victory of some evil characters, making you control them.
this gives the game some more fun to play it!
Have fun with it!
