Couldn't watch it live but just finished it up now, skipped through a few parts. I've got to hand it to MS, they've really done a great job tightening up their conferences over the past couple years in terms of just showing games that you can play soon. Less talking and extended segments on games to kill time. They've also done a great job with the variety of games they are showing. 10-15 years ago every game was some grey muddy bro shooter with excessive amounts of gore. They've still got some of those games in there, but they've also got a lot of great looking titles that have a more kid friendly aesthetic.
I still won't be buying a next gen console for the foreseeable future, but if you've picked up a XsX/S, I'd imagine you'd be pretty happy with what is on the horizon.
