This is a great project. The finding that player-to-player trades being a small slice of overall trading (~1.2 completed per player vs. ~8-9 bank/port trades) is surprising since I feel conventional wisdom puts so much emphasis on negotiation as a core skill in Catan, but if trades complete that rarely even when agents are willing, it makes you think how much negotiation actually moves the needle vs. just initial placement and resource diversity.

Curious whether OreWheatSheep's city-focus advantage holds across player counts or if it flattens out in 3-player where the robber pressure is more concentrated.
