This wasn't quite clear from the English translation.
Basilica: The Brutii player can try to fulfill the Favor of
the Emperor requirements, provided that he played the Favor
of the Emperor action card and that no other player
claims the face-up tile ahead of him.
Capitoleum: The Brutii player can choose an official tile
that no other player chose this round, including one that
a player owns from a previous round, provided that he
played the Official action card.
The phrase ahead of him confuses me. If the Brutti player is not always last, how do you determine his turn position when resolving the Emperor's Favor tile and the Official Tiles?
If nobody controls the Legates, is the cost of a Legion 0?
Does the Brutti player always use all 6 Action Discs each round, even in a 6-player game?
