Thanks @sgh@lemm.ee for a great game, and congrats on the win!
Expansions used:
Traders and Builders
Bridges, Castles, and Bazaars x2 (sans bridges)
Festival
King and Robber
We also added wagons, enabled inns, scored the King and Robber Baron incrementally throughout the game, and chose to make 2-tile cities worth only two points (a la pre-2002 scoring).
