The dragonball z budokai games were outstanding until the budokai tenkaichi games came out. Dragonball z (budokai 4) infinite world's gameplay is just like budokai 3 but there are some changes in this game. This game can run on 60hz by pressing the L1 + L2 + R1 + R2 buttons all together at the language select screen when you switch the game on. The stuff this game has to offer is...
Dragon mission - In this mode you play as different z characters only when you complete the game and go back to that saga ,when you first play this mode you play as goku as he goes through the saiyan saga ,frieza saga ,cell saga ,majin buu saga and the dragonball GT saga (there is a hidden story after the gt saga). As well as fighting in this mode there are also activities in this game.
On the saiyan saga there is chasing after raditz where you pass through checkpoints racing against the timer ,travelling along snake way racing against a timer jumping through checkpoints and collecting coins and other things along the way ,on king kai's planet catch bubbles and train with king kai timing your energy blasts to destroy some bricks and kid gohan training with piccolo where you press the button on the screen at the right time.
On the frieza saga there is the race to guru's house where you pass through checkpoints in order and avoid getting caught by vegeta ,goku training on his way to namek where you hit the buttons shown on the screen as quickly as possible ,hit piccolo with chuckle beams when playing as frieza ,hit frieza with destructo discs when playing as krillin and escape to frieza's spaceship as super saiyan goku racing against the timer while passing through checkpoints.
On the cell saga there is battling in the hyperbolic time chamber playing as super saiyan goku against super saiyan gohan and also playing as super saiyan vegeta against super saiyan trunks pressing the buttons at the right time ,vegeta training to become a super saiyan by pressing the buttons on the screen as quickly as possible ,cell (1st form) escaping piccolo while passing through checkpoints ,dragonball hunting where you use bulmas dragon radar to find the dragonball and tien stopping cell from absorbing android 18 (this can be a difficult mission).
On the majin buu saga there is playing with goten where you fly through checkpoints while trying to avoid goten and videl learning to fly where you press the buttons on the screen at the right time.

Warriors training - Practice your moves.
Warriors room - Here babidi and dabura wait for you to sort out your skills for your characters and you buy skills from the shop here.

"You can only do the transformations when you have unlocked the skill for it and you have to upgrade the skill to max level to get all of the transformations for that character"
As this is one of the budokai games you can't hide behind things like in the budokai tenkaichi series ,you can't fly anywhere only forward up or back and other things and the fighters road is just long and completely boring as you just fight enemy after enemy and janemba has a sound flaw ,you can only play as his 2nd form but he has his voice when he was in his big yellow first form. The graphics are impressive with the cell shaded characters and there are some movie sequences in this budokai game from the dragonball series when you play through dragon mission. This dragonball z game isn't the best one but it's still worth playing it.
