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.
Adaptation Displacement: Anyone ever hear of White Bear and Red Moon? It was a tabletop wargame from 1975, and it was the game where the world of Glorantha was first introduced. Now, both the RPG and the video game are far better known.
Base Breaker: The ducks. Either they're a marvelous example of how non-bogstandard the setting is, or they're a distractingly silly blot that spoils the mood.
