This also relates to my mention elsewhere in this discussion of what used to be called "special snowflakes" (before the birdsite ruined the word "snowflake"). Some people want novelty and creativity above all in their RP, and that doesn't always come with a sense for how to balance that with intended theme or tone. And as you point out, if *no one* is playing things remotely straight, things can become farcical, or at least like an "Oops! All Foils" situation with no requisite normal.
