If you start off in the middle of a desert or jungle, do you restart the game and try to get a more favorable start position, or do you just go ahead and play it by ear? The reason I ask is because I have recently developed a bad habit of making like 3 cities, then realizing there is a huge desert/jungle nearby, so I start over. This leads to me not being able to really play ANY games, because I always find something wrong. I wish I would just play the damn game no matter what happens. 
What do you guys do?
