In Suburbia you track your population, reputation, and income. The goal is to have the most population when the cards run out. Income is needed to purchase tiles to increase your population.
As I understand from what the rules say about reputation is that in the event of a tie with population at the end of the game, the one with the highest reputation is the winner. My question is, does reputation do anything else in the game other than that? If that's the only reason for it, and ties are pretty unlikely, I have no reason to keep it up.
