Even if a Skyrim or Fallout wouldn't make a perfect transit into a co-op or MMO game I'd still love to ply either of those game types. Just give me a friend who can drop in drop out and if you gotta remove time affecting shouts, spells, and in the case of fallout V.A.T.S. Or just do what killing floor does. Frankly I don't care I just wanna play fallout with a few friends. They don't even have to be able to import export characters just have them be a random (or chosen) model scaled to the players level with some simple starting equipment.
