The answer: Fuck yeah.
Have you ever wondered what it would be like to play a video game if you had three hands? Well wonder no more, because it’s the best thing since jello (because everyone loves Jello). That’s what it feels like to play ME3 with Kinect. Never have I felt so in control and connected to a game. Ordering you squad mates to use their powers and take cover feels amazing, and all you have to do is speak. It’s nothing less than genius, and it’s an experience not to be missed if you consider yourself a fan of Mass Effect or just cool shit in general. So yes, ME3 is indeed better with Kinect.
