Computational, and also how much does it add to the &#x27;fun&#x27; in the gameplay? City builders aren&#x27;t about modeling how real cities work, they&#x27;re about providing a fun gameplay experience. Which is fine, but orthogonal to the question of whether modeling agents in the way mentioned is the &#x27;best&#x27; way to model a urban system (to which the answer is a solid &#x27;maybe sometimes&#x27;, but that&#x27;s a different discussion...)
