First of all, just to make it clear, I'm a regular viewer of TB's content, I enjoy his work and consider him one of the more reliable reviewers/pundits in gaming. I agree with him on most points, and generally am neutral on most of his other stuff. However, I can't agree on this one.
Don't get me wrong, he argued it all quite eloquently in his video. Those are all solid arguments. However, they are predicated on an assumption that goes contrary to empirical data. That assumption is that Microsoft isn't a lying piece of garbage. Which it is. MS has been swearing that it's coming back to PC for a decade now, and it never does. At most, it tosses a port or two our way, often in a garbage condition. And it's trying to lock down PC gaming in a most unpleasant way.
As for its multiplatform releases, I just have two words for you: Quantum Break. Yeah.
Basically, MS has been shitting on PC gaming for many many years, and its practices were horribly anti-consumer. I don't buy this schtick of theirs for a minute. They are being shit on by Sony and they know it, so they're grasping at straws. They talked a bunch of guff and basically said very little. Meanwhile, Sony came in, whipped out their massive metaphorical dick made of awesome games, slammed it on the table and just said "Look at it". And it was beautiful.
So, to me, Sony "won" in as much as anyone can "win" E3, and this is coming from a PC-only gamer who knows he'll likely never get to play most of the awesome shit they showed off...
