First-time poster here, Civ4 newb in general (just got my first win on Noble). When you're thinking about where to move a settler to build a new city, do you guys use that blue circle recommendation or ignore it? Sometimes I will be looking at the yields/resources and think that one square is a great place for a city, but I don't get a blue circle. Sometimes I see a blue circle, go towards it, and think that an adjacent square would actually be superior to the circled square. Should I use my own judgment, or trust that the AI knows what it's talking about?
