Honestly, I just really liked how they did their press conference. They jumped right out of the gate with the announcement of the Xbox one X, then they just went straight into a game after game after game.They didn't have much boring talking about the game they were showing.
Forza 7 looked extremely good in 4k. That Anthem game looked really good as well. They had a few other triple A titles that looked good too.
I still have to watch the Playstation conference, but before watching it I believe Microsoft won this E3 with ez.
