Apparently I'm in the minority, but I honestly liked the campaign in the one CoD game I've played more than the multi-player. It was fun to blow up the Eiffle Tower. I was like "take that Frenchies."
But, in my opinion, Skyrim is closer to an FPS than it is an RPG. So, in a way, the game has been CoD'd out. Or Halo'd, or BF'd. Whichever you prefer I guess. I still like Skyrim, but I don't think its an RPG.
