Fallout has always been about the player using their instincts to decide how to affect the wasteland in the long or short term. Solving Fallout quests as a group would be a nightmare.Having a co-op partner would mean having to talk a lot to coordinate who takes what course of action. A huge part of the appeal of Fallout is the quiet and the solitude.
If so, this would limit who gets to play the game and how. The game has to retain something of its turn-based roots. Making it mandatory for the player to cooperate with others would take away from completionists’ achievements. Fallout has been a traditionally solitary experience, following the exploits of a single main character (the Vault Dweller, the Chosen One, the Lone Wanderer, the Courier) as he or she travels throughout the wasteland.
