I downloaded the demo off the PSN today. After paolying both available battles I will have to say the battle system is quite a bit better then Budokai 3. The gameplay is faster paced and the attacks seem just as fluent as they are in the show.
The drama system is an interesting addition that changes up the gameplay a bit.
Graphically I was not expecting as big of an improvement due to the cell shading. The game truly looks 300% better then the PS2 games.
Is the game a restart of the budokai series on the PS3/360, probably. Is this next-gen restart worth buying into the game. If your a fan, definitely.
