1. I couldn't find anything in the rules that says opponents are REQUIRED to give each other passwords after a game... How can I make an opponent give me the password to their save files after a game?
However, there is a clause:
6. Players must make daily saves, keep them until the end of the tournament (i.e., until the results are announced and the winner is awarded), and provide them upon first request from the tournament organizer/judge/member of the arbitration committee.
If the saves are missing for any reason, the organizer/judge/arbitration committee will use the saves provided by the opponent. Claims against the opponent or judges will not be accepted in this case.
I plan to write a separate, detailed clause about using mods, so I will take this into account as well.
2. If both opponents want to start building cities FIRST, how do you determine who builds first?
