I control 146 corporate branches for 146 points.
I have 27 cities at size 10+ for a total of 54 points.
I suffer a -259 penalty for how long it took me to win. My final score is -59 (146 + 54 -259).
350 points at 1 AD
488 points at 1500 AD.
-59 points at final.
779 is my total score.
I have no question I lost this event. This event was setup for a win by cultural domination, and I suspect the winning score will break 1000 points. I would have hit close to that with the 200-point bonus for a cultural win.
