If bethesda was to make a whole new world just for two players, would you like the idea? some ideas they could do is by making some more perks for it and lots of new quest's, new armor, weapons, characters, towns/citys, new enemy's, new creatures, caves, and tons more. So if you think this idea is a good one. plzz just comment and tell me wat u think or if you have any ideas??
The game engine wouldn't allow it; it was intended from the beginning to be single player. There is a separate studio that is working on something multiplayer; hopefully they will release information on their project at some point.
If you want to discuss multiplayer or co-op, use this thread: http://www.gamesas.com/topic/1320106-official-tes-multiplayerco-op-thread/
