That's not to say that the game is actually BAD. The fact is, this doesn't play much like a beat-em-up, unlike its cousin 'Budokai'. It plays unlike any other game, really. You get a large landscape in which you can freely move on any axis; you can fly up at will, move back or forward or side-to-side (or anywhere in-between).
Using 'Ki' energy, you can blast your opponent with great huge beams of energy, or multiple 'shots' of energy. You can also speed toward them and perform a 'rush attack', which is basically a series of very fast and stylish melee attacks. Alternatively, you can just beat each other up close up, or teleport around each other whilst fighting.
The graphics are supposed to look like a 3D version of the animated series, or the manga (Japanese comic), which it accomplishes very well. The characters are nicely detailed, and the attacks are very nice and flashy (and rather well choreographed, for lack of a better term).
Once again, I will state that this does NOT play like a beat-em-up. The screen isn't side-on so that you're seeing both characters in profile; it's more of a 3rd person over-the-shoulder kind of view. Thusly, I would have thought that if you're looking for something like Tekken, or Soul Calibur, try out Budokai. But if you're looking for a game that delivers a very accurate portrayal of how the Dragonball series' really went, then give this a go. The 'story' mode is VERY long, and you can unlock up to ~150 characters and character forms (for example Goku, Goku Super Saiyan, Goku Super Saiyan 2 etc), so there's quite a lot of replay value, especially when played with friends.
