Not sure what is meant in the forums about mirror games?

Generally it means that in multiplayer, using the PBEM+ system, when you create a given game matchup, it system also creates another game at the same time, with the sides swapped. It means you can play unbalanced scenarios, but each player needs to deal with the same mismatch.

If you ask the question in a specific game forum, you are likely to get a more specific answer.
