Have you noticed how small azeroth is?

[unholytestament]

Most of the ZOMG HUGE game worlds are empty and boring. While realistic, realism isn't very exciting most of the time

Elder Scrolls 2: 487,000 sqKm. (Tamriel)
Elder Scrolls 3: 25.7 sqKm (Vvardenfell)
Elder Scrolls 4: 41.4 sqKm (Cyrodiil)

There's the actual sizes for you.

Based on that, I think the world of Elder Scrolls is > than WoW

Is that the lore sizes or the in-game sizes, though? Based on the numbers on WoWpedia (which may or may not be accurate) the lore Azeroth is something like 280 times the size of what's represented in-game.

Daggerfall had a huge world, as in, it would take hours if not days to go from one side to the other.

I was under the impression that Daggerfall didn't actually have an open world, just cities and dungeons. I haven't actually played it though, so I could be misremembering.
