I have the original Bleach game on the Gamecube, the one I believe the Wii version's fighting style is based off of. It follows up to the Soul Society Arc with a few bonuses (like, Kaien is in the game).
It's not exactly a perfect game to be honest. Some of the characters are broken. Byakuya is totally cheap. And it's hard to play with Chad (as it's so easy to see his attacks coming). Hitsugaya is hardcore and so is Urahara. And, for the record James, Orihime is great too. I would love to play the one on the Wii as it's supposedly been beefed up with a better system and a lot more characters but sadly there's no action replay for the Wii yet.
And I have two friends with Heat the Soul 4, the gameplay looks a lot similar to the one I have on Gamecube. But I can't stand how Urahara plays (though, I had no idea what I was doing when he handed the game to me..). He's so... stiff. Angular. Not like the fluid style he's shown in the series and in the Gamecube game. But, like I said, I didn't play with it long and I had no idea how to play at the time.
I'm wondering if I should pick it up. Is it Wi-Fi enabled or just Ad Hoc? I hope Wi-Fi.
