I am quite familiar with party-up dungeons in TESO but in all vids released by them so far they show no evidence of normal caves&fortresses around...will there still be these fun enemy filled areas in the upcoming release? That's one of my all time favorite past times in Elder Scrolls...if so will be there ship loads like previous games?

I think I read somewhere there will be.
In any case I should also hope so

I dont see them leaving the underground fortresses out. We will just have to wait and see
