I think it would be pretty fun to fight others characters in a online arena game. There could be a system that lets you search for a player within 3 levels of you and the winner gets rank points ect... What you guys think? I doubt they would do it though but it sounds like a fun addition.
The only multiplayer I would ever see them doing.... but definitely not this time around. And the infrastructure needed for such a small feature... I just never see multiplayer getting into TES for some reason.
