Great combo system combined with Dragonball Z makes this a great fighter for anyones collection.
This game might not have as many different gameplay options as i'd have hoped but the ones it does have have a great ammount of replay value, the Z Survival on its own may take you within 3 days of you having the game before you are good enough to defeat it. (Minor spoiler)
Too my annoyance you don't actually get anything from Z surivial but when i look back on it, it was certainly worth the challange.
This game may not have as many characters as the previous dragonball z games for ps2 but each character has its own strengths and weaknesses unlike some of the practically clones characters from the previous games.
People may have complained about the lack of special attacks in this game compared to some of the earlier budokai games however it is how you put these limited attacks into combos that will affect how good you are, not the ammount of them at your disposal.
The sound is pretty good quality for such a cheap game however Chi Chi's screeching can get rather annoying after a few days spent playing this game.
