it could be fun with a team play mode, like join another players single player game, and he will replace as a companion player only, and reset to his level and get gear from him and only can help him in battle so his single player game is still his
so in that way people can play together in a co-up version, all gear most come from main single player, so its still a single player game just with a helper, and no other companion then ,1 if its a quest fallout companion, then ok
it could be a total new fun game , and i know that helper cant run off and do bad stuff without main game player you will have to stay near main gamer and help and such you will get no dialog, ,but still think it could be fun with a friend over (skype or other talking program)
and if player helper quit , he can get his fallout companion back and continue his single player game...
