What I'm really hoping ESO keeps to the game is the presence of npc's ability to attack each other in the game. Now, there should be zones where they cannot bring their craziness to towns, for example, if people don't want the craziness, or players finding exploits, etc. However, I feel that if the developers go the same route other mmo's do, and just keep the same [censored] formula of npcs outdoors having a specific spawn location, and not being able to leave within a certain radius of that spawn location, then they will rip out a good portion of the soul in an elder scrolls game: the element of freedom, the sandbox-like aspects.
With that in mind, I also hope this isn't one of the thousands of mmo's that don't allow you to sit on chairs... It's a relatively little thing at face value, but I take the policy that everything is intertwined with each other, and that if this feature is missing from the game, and other features like it, then it would be saying a lot about the game already.
As well, once again, let's bring in the lotro style of instrument playing to this game shall we, if it's not already in.
