We all know that ESO will be on a mega server for your platform,but what do you think about extremely crowded areas. I can guess there will be one town or something that's best for banking/buying stuff. And if it's anything like other MMO's your just gunna see tons of bodies walking quickly through each other. Anyone think this will be a problem?

No more of a problem than tons of bodies clogging up narrow areas because they can't get past each other.

I think they will make it so you can walk through people. It would be a nightmare if you couldn't. Because then people could technically block you from going places.

It's already confirmed that they'll be no CD between player characters and NPCS and each other.

As a side note, there is no collision detection, so there will never be the problem of people blocking off areas for others.

On topic, even though it's one large mega server, there will be instances that segregate players, I understand there's a priority where you are placed with friends/guild mates first. To have no instancing and just have tens of thousands of players in one area will be ever so slightly laggy for some I'd imagine.
