Here's what Microsoft has changed or added
After seeing the Xbox One friends list in action -- that panda with the bling is still cracking me up -- Microsoft has another video showcasing multiplayer in its various forms.
This is more of a high-level overview than anything else, so expect to hear about previously-talked-about features like SmartMatch, the revised reputation system, recording gameplay clips, new types of Achievements, and the cloud.
To that end, we're not going to be able to blame "host advantage" any more. It's served me well over the years. I'm going to need to think up a new excuse to shout between expletives.
