In Oblivion you had an arena, imagine an arena online.

Apparently, current buzz is since the director of the game was a major dev behind the Dark Age of Camelot mmorpg, the whole game will be PvP. If this is true, I'll never even bother looking at it. Open world gankfest PvP = no money from me.

It'd be awesome to have clan fights in an Arena.
