OK maybe I'm playing wrong here. I've been mostly having Dale bot take the most expensive market spot. It's not necessarily the most expensive tile. If that's the case, It make it much more interesting.
So I take it he takes the most expensive tile. Not the Market value is that correct?
Yes, the tile that is most expensive to buy, not simply in the left-most spot. You can sometime manipulate AI's buy so it's not optimal.
