Out of all the Playstation DB games, this is the one to get.

When I first heard about this game I thought it wasn't possible to see 3 on 3 fights at the same time. I was wrong, not what I expected though, but damn was this a great game. It goes through all the sagas from the Saiya-jin saga up to Kid Buu. My first impression was with the graphics not being as good as I thought, it would stink, playing it certainly changed my point of veiw. The aim of the game is to fight and get the balance meter to full, Blue being your side and red being the villain's/second players side, once it's full you will unleash a special attack depending what character you have chosen to be. Being able to change characters in game and being fast pased was good, cause I never thought being confused would be so fun, trying to see where your character is amongst the other 5 people fighting. The music is one good point of the game, it captures the music to the anime pretty well. The sound effects are great too, keeping the original sound effects and the Japanese voices (Although Goku's voice still scares me)

The best part of the game for me is the multiplayer feature, it's better playing with a friend who knows how to play it, but it takes a while to finish

In my opinion this is the best Dragon Ball Z game for the PlayStation and if you don't own it your definitely missing out on a great game that has made Dragon Ball Z proud. So out of Ultimate Battle 22 and Final Bout, this is the game to get.
