Sony killed it. Wasn't even close.
MS had a couple things that interested me -- the Scorpio announcement and the Windows/Xbox integration. I'm looking forward to seeing how both of those turn out. But the games themselves fell flat for me. It seemed like mostly a rehash of last year, with nothing much new. Doesn't help that I don't care much for their tentpole franchises. I don't think I'm the kind of gamer MS is courting.
Sony showed a bunch of games I really liked -- God of War (surprising), The Last Guardian (release date, hey), Days Gone (big surprise), Spider-Man (yay, me happy), Kojima's new game (overrated and pompous doof, but I'll buy his game), Horizon Zero Dawn (looking good), Detroit (looking much better than last time), and a Crash Bandicoot remake (I like the resurgence of these old games). There was also Abzu (beautiful), Bound (a surprise, also beautiful), and then visually stunning, original games like Gravity Rush 2, Nier, and Persona 5.
It was a great show. Almost pitch perfect.
The only thing I'd change would be to add more of the weird titles they have, rather than rely so much on games designed to appeal to the mainstream Western/European audience. While impressive, the games did have a sameness to them, when all lined up back to back like that. They have a lot more variety they could've shown.
