Dice City: By Royal Decree

From the publisher:

The Queen is taking a personal interest in the development of your cities. The type of locations you construct, where you build them, and even your capacity to gather resources or build armies may all come under her scrutiny. Trade is also high on the royal priorities. Winning the prize, and becoming the next great capital just got more interesting, exciting, and challenging!

Dice City: By Royal Decree comes with a new and separate trade board, extra dice for that board, and new strategies with Queen's Plans cards. New locations require you to be very specific about when you use them. Victory is in your grasp if you can just roll, build, and win!

You need the core game to play with this expansion.
