Bethesda franchises are no place for MP content (just look ESO). Good games that succeed in what they set out to accomplish are hard to find these days. Its like finding a large rare ruby in your back yard and spray painting it green because you like emeralds. Your ruining a beautiful gem because you would rather have something else. Fallout is not a MP experience, just like mass effect, dragon age, and the witcher are not MP experiences. It ruins the ideals of what the games are.....a solo experience.
Further more the idea that MP is even more deplorable after the fact that now all the consoles will be reicing mods. Yes there are ways to circumvent or correct the game experience for coop or mp with mods but why would you want that? Skyrim is a good game made great by the countless hours people have put into modifying it. Bethesda even stated that the modding community kept skyrim alive much longer than anticipated. So why would you want to remove your personalized experience to play with others in a game where that was never even a goal of the franchise to begin with?
