The Xbox One's got some interesting features to help with multiplayer and to try to weed out those that are trolling in games. The reputation system looks to help with giving you players that are not going to be jerks.
Dedicated servers are being used now rather than listen servers of old. That means there won't be one person who's going to have the advantage as there will be a dedicated computer that now hosts the game. And with dedicated servers, there will be more players supported now.
Of course, there's more features as well such as DVR, sharing and so forth, which the video touches on below.
Also, it's kinda nice to see Doty, who I shared a room with at E3 one year. :)
