I'm not one to use this phrase a lot, as I feel it's used too commonly when discussing games....but actually speaking dialogue gives me a hyper strong sense of uncanny valley. You read the dialogue choice...then Shepard speaks directly after, saying something completely different?
Making it so that Shepard doesn't say something after you speak the dialogue would help...but Biowares whole thing with this franchise has been that Shepard doesn't really say exactly what you think. They also have to account for 90 percent of the people that won't be using kinect with this.
And then you have those times when he talks without you saying anything...just very strange looking to me.
I'm not sure if this feature was put in for immersion, or if they think it's easier to speak then to move your thumbs, or if they just thought it was "fucking cool" or what.....
I think it's really cool that Bioware is implementing this. Don't get me wrong, obviously somebody was going to try something like this and I can't think of many that would be better suited to give it a shot (As Bioware still makes dialogue heavy games). But...that looked very weird to me. Obviously, they are adding this to a franchise and to a game that started out without Kinect in mind, I'm sure that Bioware and other studios will improve it, but my initial impression based on the short demo can only be described as creepy.
Maybe when you play it yourself it's better.
With all that said....I personally like the combat kinect controls. Nothing against that. If my hearing was correct, I don't believe that Shepard says anything when you give combat orders. Also, it's obviously more natural, giving short concise orders like that is far more compatible with kinect right now than trying to have a freaking conversation.
