One rule that we just realized we had not been using was the Final Main Action. According to the rules, after the last round card is resolved, each player gets one more main action and is allowed to choose a building that is already occupied by another player (but not the building that they themselves already occupy). Had we read that rule and used it properly, I would have had an opportunity to use Shipping Line to ship my coke and some other materials for a pretty big point move. But Kathy pointed out that had she known about the Final Main Action rule, instead of sitting on the Shipping Line for her last two or three turns, she would have moved off it and then moved back on it again for another shipment and more points. So we think the outcome of the game would have been the same, although we would have played our last several actions differently.
We're really fond of this game, and we definitely want to continue playing it to get familiar with how the various point-generating engines work.
