Here's a little story I just wrote:
The child walked through the park, and came to an embankment. She thought it would be fun to roll down it, and so she lay on her back at the top of the slope, and gave herself a push. Off she went, rolling down the hill!
As she tumbled down, it was the sounds that excited her the most - the swish of the grass, the wind, the noise of other children and her own delighted screaming, all rendered with a curious rhythm by the rotation of her head, her ears being covered on the left, then exposed, then covered on the right, then both exposed again, all the way to the bottom.
When she stood up, swaying dizzily, all the could think of was racing back up to the top, so that she could have another go! But her father insisted it was time to go home. Rotation, rhythm and joy were soon forgotten, replaced by a sense of tiredness in her legs, and the boredom of the humdrum evening routine.
The sun rose the next morning nevertheless.
So did my story model: gravity, body shape, hearing, wind, walking, balance and dizziness, muscle fatigue, parent-child relationships, bathtime, and the rotation of the earth about the sun?
If yes, then your threshold for
modelling is lower than mine.
If not, then that's why I don't see any modelling in the typical RPG.
