Hi J R,
Can a Villa double the score of a Temple?
No. Villa's only score Romans, not Buildings.
Can a Male-Female Citizen pair score both for their marriage and for the Temple they're adjacent to? (The second Villa is scoring for the Senators).
Yes, a nice combo to pull off. You could also use that Villa to score 3 points as well (if you weren't using it for the Senators).
Thanks for playing Micro Rome!
