This is a tech demo, so don't expect much from it. You'll be in an out in 20 minutes tops. With that said, it's really cool to see how games might look down the road. I wasn't necessarily blown away, but I was thoroughly impressed. I also liked the secondary mode where you can walk around the city and play with the graphics options to see the different layers of architecture at play. I was fascinated just tinkering and exploring it.
