I was there on sat afternoon, cool event, I was expecting more people, not at I'm complaining , it was easier to actually play something; main thing is controller felt very good, xbox itself was much smaller than I expected from looking at pictures,
After playing games there, Ryse is def a day 1 purchase for me, same with dr3; ki is obvious since it's free, I'm not a fan of the genre but game looks good and is fun to play.
bf4 looked very good, so did f5( although that one could use a little antialiasing , especially when you view the car in the garage, hopefully that will be updated before release)
