After playing through the demo, I must say that I really liked the kinect functionality. It makes the experience move along much more smoothly. They also upgraded melee combat significantly! Which it desperately needed.
The graphics seemed to be about the same quality as ME2, though, so if you're expecting a graphical upgrade you may be disappointed.
The action and gameplay, however, were just as good as they ever were. And even though the demo was only 2 levels, it really got me hungry for March 6th to get here! I've gotta finish my 2nd playthrough of ME2 before then!
Has anyone else tried the demo? Or the multiplayer?
