7. Multiplayer
This would be a very welcome addition to the Fallout franchise. Bethesda is already experimenting with multiplayer with the Elder Scrolls Online, but doesn't need an entirely separate game for Fallout. All people want is to play with a partner to complete quests and just have fun in wherever Fallout 4 will be set. It could be a very good addition and would bring many new players into the franchise. Now, we're not asking for a complete multiplayer matchmaking experience like Call of Duty or Battlefield, but a co-op capability would lengthen the game by a considerable amount.
