Trade Metropolises are about as rare as Capitals are. However, the Official Announcement did say that there will be more TMs than Capitals, because its population requirement is much lower than that of a Capital.
Inside the Trade MetropolisEdit
When you first capture a Trade Metropolis, or "Metro" as they are referred to, the castle view is instantly maximum size with level 3 walls, gates, towers, and keep. Instead of the Royal Storage, which is found in a Capital, you get a Merchant's Storage, and instead of a Palace, you get an Emporium.
The Emporium costs:
- 1,199,000 Stone
- 1,149,000 Wood
