I think the game, and others like it, would be ten times better if you could co-op it. It doesn't matter how fun the world is or whatever, but dungeon crawling massive dungeons just gets a bit boring after 60+ hours. Just having a friend along would eliminate that I think. Also so many wonderous things would have been so much more fun to behold with a friend. Those of us who played Red Dead online spent so much time just riding about, stopping and going "wow dude look at the sky/horizon/etc etc" and admiring it. I want that in Skyrim.
