I bought it yesterday and I'm loving it. I got it because it's a pretty fun game for Multiplayer and a lot of my friends like Bleach.
The action is pretty fast paced, but the controls are relatively simple. You can attack by three motions. Horizontal, Verticle, or Thrusting it forward. Which attacks get through seem to be Rock-Paper-Scissors style so switching them up mid combo works.
If you hold the A button and swing in a direction, you do one of your three Critical attacks. The Critical attacks are non-blockable and are pretty strong. If both players hit a Critical attack at the same time, you enter a Clash - a glorified timed Rock Paper Scissors game. Best outta five wins, and depending on how many you win, you do more damage. Only win by one round and you barely do anything. Win by all five and you'll take almost half their health. Holding B and swinging the Wiimote and you do a Special attack. Some better than others, obviously.
The special attacks are easy to do, and it's nice to play a Wii game where the motion detection actually works. Also, the game ignores the dub entirely. It takes place after the Soul Society arc ends, where Adult Swim still has about 10 episodes to go, and they're taking a break for an undetermined amount of time, probably a few months. The things you'll see in the game that the dub hasen't shown yet:
*The Bankais of Ichigo, Byakuya, Renji, Hitsugaya, Ikkaku, Komamura, Tosen.
*Grimmjow and Ulquiorra.
*The Betrayal of Aizen, Gin, and Tosen.
Also, for the people that hate/like dubs, I just want to throw in that the dub voice they gave Ulquiorra is really damn good. And it's pretty cool to hear that they kept all of Ulquiorra's comments involving trash...
*And if I hear a single "The English Dub sucks" comment, I'll punch you through the internet. Keep it to yourself.
