It's not so much the size, but the scale. Trying to make a 4 square kilometer desert look like something other than large sandbox or someone's beachfront property is an exercise in futility. Likewise, making the capital of the the Empire in Oblivion look like a moderately sized fortress (or being able to see the whole country from the walls) and have about the same population, just didn't do it for me.
Smallish maps can work fine for islands or caverns or the like (Crysis was fine, for example), but trying to scale down whole worlds, nations, or major cities to sizes you can jog across in three minutes ends up feeling like this:

Daggerfall's convoluted 3D map system was always a pain to use. I remember getting stuck in some dungeon for the better part of a week (real time) looking for some wizard I was supposed to assassinate. I was right about to give up, having finally found my way back to the entrance after wandering lost for days, and the guy pops out of a secret door directly across the corridor from where I came in!
I've played whole games that were probably smaller than some of Daggerfall's dungeons.

But damn, those Daggerfall dungeons! Trying to figure out those 3d maps once the dungeon was huge was impossible for me, especially since they'd lag and usually crash my computer.
