I watched the Quakecon gameplay presentation by Bethesda. Here is a link that is time-stamped to where the action begins, or close to it:

The reaction of the crowd seemed pretty muted, overall, given that this is obviously a huge title from a blockbuster publisher/dev team. From what I saw the in-game environment looked pretty good, although the loading and character creation screens were pretty rough. Over all it seemed like what you would expect from injecting the ES lore into a wow-like world. The one dungeon they showed must have been instanced, given the way the party flowed through it. The combat seemed pretty satisfying, though it remains to be seen how FPS-style targeting mechanics work in party play. I don't know if they have friendly fire. I just started playing Darkfall, which does, but I don't have enough experience yet to know whether the FPS mechanic works well in group action.
Based on what I saw I would give it a try, but I didn't see anything that really stood out as different in terms of the basic game style, and maybe that's what was behind the somewhat subdued response from the crowd.
Did anyone else watch it and not like that red glowy effect that marks enemy mobs?
