D&D is not a world simulator

[Max_Killjoy]

What is more important to a superhero game?

Rules that help you calculate whether or not Superman can leap any given building in a single bound based on factors like height of the building, gravity of the planet he's on, force of his jump, etc.

Or rules that help give you the story beats of a superhero story.

I submit that the former is entirely missing the point.

I submit that the latter is the sole province of the players and GM, and doesn't belong baked into the rules -- promoting "story beats" to the level of driving the mechanics results in the same sort of character and setting incongruities, inconsistencies, and incoherence that large swaths of fiction suffer from.
