Great idea. Perhaps in the next version of SimCity points can be awarded to those who design cities in accordance with the ideas in A Pattern Language.
But some of a city's inhabitants would prefer, for various reason, to live in a typical development, so an even more interesting model would be to create some citizen archetypes, which would feel differently about meeting people in the street versus shopping at a familiar chain, or living in a condo versus commuting to a large house they own. Then the scoring would be based on citizen happiness versus other attributes.
