The gameplay between dungeons and shrines and virtually the same-- solve a puzzle, move onto the next room.

You're missing:

-multiple rooms connected from multiple directions

-keys

-mechanics advancing over the course of the game

-puzzles designed to make use of specific items obtained in the dungeon themselves, making earlier areas with previously inaccessible spots or doors accessible after completing part of the dungeon

-mini bosses

-bosses

-enemies in fucking general

-varied theming and visuals

-plot

A dungeon is not "do a puzzle go to next room". There's significantly more to it. BOTW does not have proper dungeons. Shrines are not dungeons.
