Honestly. Local players should have a join option. Rather people on friends list should be able to join you via party and game invite. Say me and the wife want to play together, how annoyinf would that be being in the same home and never able to enjoy the vast content of the game together. Even a team of 5 at a time would be great. SOME human interaction will eventually be needed for majority to not lose interest relitivly soon. After a hundred hours or more alone, most begin to get bored alone and want to enjoy sights and adventures as a team...i know i love doing stupid things as a team making memerable moments within the game.
