My Visual Communication and Design teacher said to my class that Corridors are a waste of space while learning about Architectural design. With that said, I asked him what demonstrates a corridor, and he replied simply stating a long passage that isn't far too wide which takes away room for other areas to be constructed in a/the building.
Assuming this, can you think of the advantages/disadvantages of corridors in Amnesia, more notably Custom Stories or Full Conversions as FG/TCR did a pretty good job filling them as far as I could care.
Talking seriously here, like a flying object appearing as you walk in the room with unrealistic force is a disadvantage.
