Train games! As in, games played on the train home.
We started with Railroad Ink: Deep Blue edition, naturally. I won, 41 - 31.
Then I had three games of Regicide solo, all losses, though I at least reached the Kings on the latter two games.
We later played three games of Hanamikoji. The first game, I had the favor of four geisha, but my wife had 11 charm points, so she won. The next game, I won after the first round, getting 11 points. We played a tie breaker round which I won as well with 11 points again, though it took two rounds this time.
Finally, we played Batman Love Letter. There is a lot more luck involved at two player, but it is still fun. My wife was up 6 - 1, but remarkably I was able to come back and win.
And that was the extent of our gaming on the train. Vacation is now truly over.
