Perhaps my best built level, the Lost City of Om-Wo is a sprawling dungeon themed around Legend of Zelda: Twilight Princess.
The level's theme is "As above, so below." and is thusly broken up into two major chunks, an upper city and lower city.
The level was built in Unreal Engine, and is fully playable.

I was able to commit to it because I loved what I was doing, but boy was it sure draining.
