I love that everyone is complaining that the Kinect ONLY acknowledges voice commands for this game. You all know if it required more than that you'd be complaining about "why can't I just have my controller."
Yes it's gimmicky, and yes it seems a little slower to respond than what your hands (that you've been training to do for years) can probably do. Whether anyone wants to believe it or not, there are people out there who would be very interested in this type of gameplay. They're clearly trying to make the player more closely feel like they're the Commander Shepard by barking out orders and attempting to keep the battle gameplay fluid. I'm probably not gonna get it, but only because I don't have an Xbox anymore but for someone whose family might have a Kinect, I think this is a nice additional use for the hardware. I don't see a lot of people going out of their way to buy a Kinect just for this, but if it's there, why not get some use out of it.
Everyone wanted more "hardcore" games for things like Kinect and Playstation Move, but now that you're getting it, people are complaining.
I don't see why everyone is getting so worked up. This is an OPTIONAL feature with an OPTIONAL device that is in NO WAY REQUIRED to play ME3. Relax folks.
