i saw a person recording his character walking and running across certain regions, but I am curious what is the total combined zine of every single interior and major exterior region lets exclude dungeous, I bet its one of the largest ever desgined, Alone Cryrodil is bigger than most games.
Does any dev have an accurate data or maybe there is a way to measure it, I know its not an easy task , but size plus features and interaction is just mind blowing, Not only its enormous but dense,rich and feels alive, there is so much to do which makes zones so rich overall , easily spend weeks in one if you wish to do all,quest,lore,artifacts,points of internets etc...
P.S There are outdated sties, ESO was released in 2014, at has changed and expanded since then, We need most recent update with Greymoor expansion
