While I have no love at all for the Call of Duty franchise, or Activision as a publisher, even I can see that Black Ops 2 is probably going to be the best CoD in a very long time. It even seems like there's a shift in focus to be observed here.
What I appreciate a lot (and hope will continue being a thing in the future, seen in more and more games), is the official Youtube streaming support the game comes with - natively - on consoles.
While Microsoft expresses clear limitations for Halo 4 on Youtube, Treyarch and Activision appear to feel that active support for Youtube, streaming and even eSports is benefitting them more than bans on content.
I don't like Activision as a publisher in any way, having ruined many franchises and undeservedly outselling every other game with recycleware, but I admit that this step is a GREAT example to the rest of the industry. Open the gates for more user-generated content on the internet to promote your games, instead of limiting it to major networks and sites.
I can only hope others will see that this move is, contrary to popular management opinion, is NOT hurting their brand in any way, shape or form, and will follow.
