I say Microsoft won. Gears of War 4 looked fantastic (minus the ragdoll bodies), the Xbox One Slim is a sexy model, ReCore looks like it could be good fun, Sea of Thieves was decent, We Happy Few is trippy and worth a shot and while I hate what they've done to Dead Rising, well, it's Dead Rising, so I'll have to play it eventually. Scalebound, INSIDE and State of Decay 2 were the icing on the cake, and can't wait to see more about them.
Couldn't care much about exclusive DLCs, Forza Horizon or Minecraft, to be fair. I need to know more about Project Scorpio before getting invested in it.
