The game would have to be redesigned from the ground up so that the three cities are equidistant from each other and so that they either offer similar services so that there is no preference for ALL players to stick to one city or completely UNIQUE services that give players a strong reason to stick to one (different) city versus the others.
tl;dr: Wait for 2.0.
