It was pretty late when the conference was on and I was very tired so my overall impression of the thing is a bit hazy.
They certainly had a big amount of games with some nice reveals in there. To be honest the most exciting tangible seeming thing they showed was that Gears tactics game, which is apparently a PC exclusive. I mean Cyberpunk and Halo and all that looked cool, but it's hard for me to get excited for something that's still so far ahead in the future.
This still didn't fix their game lineup for 2018, but the announced business moves and upcoming Halo and Gears games along with the hardware tease certainly make it seem like Microsoft are lining up some big shots for 2019-2020.
I would have liked to hear some more tangible bonuses coming to Game Pass and some simple hardware announcements, like an updated Elite controller or a small camera (Kinect) or something. And what about backwards compatibility? It would have been cool if they'd announced some more solid games on that front too.
EDIT: Also what was the deal with all those Xboxes on stage? I was fully waiting for some battle royale game to be announced and be played on stage, but then no? Maybe even Battlefield or something like that. Was something major pulled from the show last minute?
