how will the people making this game deal with not allowing people into certain places that arent in the game?

will there just be an invisible wall? or a wall of mountains that you cant get through? sorry if this topic has been brought up i havent seen anything on it tho

hard to comment on this without breaking the NDA

They stated its an instanced version of your enemies area, which means you have to travel by loading screen

How interactive is the world? Can players toggle a 'walk' function instead of running everywhere? Will we be able to interact with objects like chairs, ladders, etc? Will you be able to enter houses, or, for example, an inn? How about setting up a romantic camp fire at night? Will we be able to build our resting places, for example by placing a blanket?

Walking is already available (along with a whole slew of emotes, which we mentioned above). You can enter lots of the buildings you’ll come across, but there are a few you can’t. There are tons of shops, inns, and temples you can enter, and even many residences. Right now, we don’t have any special camps you can set up, but there are tons of beautiful (and, yes, even romantic) vistas all across Tamriel that you can visit.
