For those who are fans of the series will love this, but takes a while to learn basics of new gameplay.
This new gameplay style is different compared to the other 3 Budokai games. It will take some time to get used to, but dont give up, once you get the hang of it, it grows onto you.
Dont feel as though the ones who bad mouthed the game is right, they only say that because they couldnt handle the game, because they only suit games which requires no skill, probably stuff like RPG's. (not saying they are bad, just some nerds bum them and none other games).
If you want to get the hang of Budokai 4 fast, I suggest turning down the difficulty first in order to learn the basics of the controls, and also to keep the interest in the game as you prgress. Otherwise you may end up stuck if you dont have th ehang of the game.
