Alacrist, let me tell you about my experience with Blackhand:
I am one of those seasoned/veteran gamers that, prior to the Wii, would laugh at "noob" gamers who move their bodies and controllers everywhere thinking that would help the on-screen character move around in the game.
Even with the Wii, I don't lose control and flail my arms around. Nope, not even in boxing (anymore!).
Blackhand, in one fell swoop, changed all that, and my initial doubts about the Wii's lack of responsiveness, forever.
I lost control of myself, and found myself wanting to bash the &%#$ out of whoever it was I was beating up with that baseball bat. I wanted to hurt that guy real good.
I was, frankly, lucky to have used the remote strap (something I would've swore I would NEVER have needed before), because after just 10 minutes in the game, my Wii remote flew out of my hands, the battery pack came off and the Nunchuk cable slapped me in the face after being yanked out of the Wii remote. It could've been much worse: A destroyed LCD.
I have, in over 30 years of gaming, never had this amount of immersiveness and fun from beating the crapola out of someone. Count me thoroughly impressed. I haven't had this much fun in a fighting game since... well, ever!
This is gameplay you must try yourself. Seriously. If you can overlook the rather poor graphics (easy thing to do with the control scheme) you are in for one helluva treat.
