Horutoto Ruins in XI, compared to, say, Cassiopeia Hollow. Both lower level dungeons, both pretty large.
Here's a link to the map for the Hollow
Now, here are links to the maps for Inner Horutoto Ruins (

The first thing you notice is how differently they're set up.
The Hollow is pretty much one large area of rooms and corridors with nothing really going on. A generic, albeit pretty, dungeon.
The Ruins, however, are separated into sections and are riddled with interesting sights, weird contraptions and other various points of interest. Further, they tie directly into the game's lore which Windurst players are introduced to early on in the missions. There's tons of interplay between one map and another, as well as between Sarutabaruta and the Ruins, with all the entrances scattered about, accessing different parts of it (Eldiemme Necropolis has a very similar setup).
