Well, u see, when i play Wii sports boxing, i'm going combo crazy in real life but my Mii just has like a seizure. Don't tell me anything about the sensory bar because it's postitioned at chest level on my TV, it's on the edge and not covered by everything, i have it set to above TV. Yet, still, it doesn't respond to my punches, instead, i just lean until it goes matrix and i punch a few times, that's how i win. also, When i go to training mode and that one black dude, holds up the targets, i alwasy hit him, it's like hard to aim at the targets, it pisses me off, like really, i'm trying my best to hit the targets but it doesn't respond. :C
