I really liked the humble Microsoft at the beginning of the conference. The games were great as well: it was good advertisement for multi-platform games.
Timed exclusive content for almost every multi-platform game was a smart move as well.
Halo looked absolutely phenomenal. All the debris had me wondering is this game will use Cloud computing technology.
Sunset Overdrive had amazing graphics as well; the cutscene was borderline CGI, with animation that would not have looked out of place in a pixar movie.
The quality of my stream was pretty bad, but still, those 2 games shined through.
All in all a pretty solid conference. I would give it 3.5 out of 5 stars
