If this was purely a game and not a fitness gadget I would be interested. I'd be really curious if it was a good boxing game + this stuff to recognize movement from your hand (not these bands though). Would be cheaper too. But anyhow punching big robots/creatures just seems wrong - they seem to be heavy and my hand would just hurt lol. Also, when you use the word gamification it makes it crystal clear your game design knowledge and intentions are very limited. Don't take me wrong, I'm just being plain honest. Games > fitness, and this would make an awesome game. Particularly if it was competitive multiplayer :D (boxing and coop also doesn't seem right to me)
