Ok, so this game is pretty good I would say, the voice acting is good (because they are done by the real Bleach voice actors), and graphics are normal for ps2 and the music is ok. Where this game goes wrong is the gameplay. The gameplay has a few problems.
#1: Lack of abilities for players.
#2: Not really any "oomph" in attacking.
#3: Some characters are quite overpowered,making it slightly frustrating.
#4: Mission mode is a bit annoying, as some of the missions are seemingly impossible.
#5:The bankais/releases are ridiculously over powered, and also lack "oomph"
Now I know the Bankais/releases can't be too lack lustre, but really, it needs a little less damage increase and it needs more abilities. For some reason, your special moves get taken away when you go Bankai/release, this is a bit annoying as you would think a good Bankai/release would have some ultimate move. Instead of increasing attack damage, the developers should have increase attack power slightly, and give the bankai/release an ultimate move. however, the different characters play quite differently, so that adds a good variety.
The game is a good go for Bleach fans, but it isn't going to convert any people. It just simply isn't good enough. I would say the game is worth buying, if your a bleach fan. Otherwise, leave it alone and get another game.
