You've made the resolution to maximize your swag in 2013, but the problem is that you're a socially awkward nerd and can't even fathom dancing in front of people, much less impressing them with your repetoire of moves. Dance Central 3 may not give you the confidence you need to tear up the dance floor, but it'll at least give you a few secret weapons in case some hottie decides they want to watch you break one out.
