no niben basin.

in other words.. the huge body of water slap bang in the center of the map where the imperial city/bravil were.

without this.. the size of the world will seem bigger despite being around the same size.

also cyrodil was one huge bowl shape.. you could see most of the map from frostcrag spire

I predict skyrim with its numerous peaks/valleys/canyons will be more Vvardenfell than cyrodil in topography.
