"If authenticity was a fluid with measurable viscosity, then NBA 2K 13 would drip with it. It looks, feels and sounds like an actual game of basketball. The player models themselves are far from visually perfect, and animations have the odd stutter, but the way they move and collide is spot-on. During a game, mascots jump around like idiots or fire T-shirts into the crowd with launchers. Cheerleaders prance around, and cleaners buff the playing surface."
