Awesome game
It's fun play with friend, and you can for fun put on options japanese voices. (which are really scary). Not much complaint, only that you play sagas so fast and get characters easily. Game has no levels like in Budokai 3 but there is evolution Z there where you can give characters for example: strenght 5+. There are some new characters such as: great ape, evil buu, super 17 and Master Roshi and all. Game has still the same things as in budokai 3. If you do kamehameha (or other) attack with both characters you'll have to use analogs. Game has Ultimate battle where you can choose your character and aim to the best. You will start from fighting against Hercule and then you have to go better from 100th to 1th (it takes long). Enemies become harder and it's better if you use evolution Z.
World tournament is also there! You can choose Cell games also. In world tournament isn't very good because ringouts come too easy, for example. I was Piccolo and when battle started I used special beam cannon and it was already ringout. Cell games doesn't has that thing. It's fun to fly everywhere on the game because places are cool looking. You can also find dragonballs on Z battle gate at places you'll have to destroy first. Buy this game and play it!
