Been playing Killer Instinct and Ryse. Both are super impressive, for different reasons. I've also been a big KI fan since the originals came out. Ryse looks downright amazing and the execution/combo system is satisfying. A tad repetitive, but the satisfaction makes up for it.
One feature I'm in love with now is the HDMI pass-thru. I have an antenna box going through it that the IR blaster on the Kinect will control. So now I can walk into my living room, say
Xbox, On, it fires up, turns on my TV, and the antenna box. From there I can tell it to go to the OneGuide and select whatever I want to watch. I can aslo tell it to turn up the volume on my TV. I have a $200 logitech harmony remote that was just rendered useless.
