These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: DOOM: Repercussions of Evil
Applicability: It's common courtesy to write a review of this fanfic as if it's a literary classic studied in English classes.
Fridge Brilliance: The collapsing ceiling that traps John can actually happen in the original DOOM games; some crushing ceilings do not retract upward, and if the player survives the crushing part he will be immobilized inside the architecture.
