In Oil Springs, can each player upgrade only one city to a metropolis?
A clarification posted for the scenario answers it, and no post contradicts it.

No. All metropolises are shared by every player, so one player may build several. The pool runs out after four in a 3-4 player game, or six in a 5-6 player game.
