I actually got to play online! Hurrah! It took AGES of waiting about in the lobby for others to join though. Finally had four players, although one quit instantly.
And then, as soon as someone was two points ahead, someone else quit. Idiot.
However, I did finish the game with the remaining player (a German guy) staying in right to the end, even though it was clear he had no chance of winning for the last 20 minutes or so of the game. So well done for him for sticking around anyway!
Sadly, one of the (moderate) AI players won, having two secret Victory cards meaning although I thought I was winning, I obviously wasn’t. Bah. I only needed one more Ore card and I’d have won.
