A combination of a number of factors:
1) Area's resolve so quickly that you rarely experience the tit-for-tat opportunity
2) The neutrals mean it is rarely a simple case of majority
3) The sheer number of spaces and opportunities mean that you can be competitive without having to resort to tit-for-tat.
4) The second place prizes sometimes mean it is not worth fighting for the first place, but instead concentrate somewhere else and score both a first and a second.
5) The mayor cards are significant amount of points and as each player has different objectives the tit-for-tat is reduced.
What Royce (very effectively) said.
