It's X fortnight in our #BoardGamesAToZ challenge. We have exactly one game that starts with X:

It requires more than two players, though, so we'll have to wait until game night to play it.
Game night is scheduled for the very last day of the fortnight. Letting everything ride on that is just asking for us to come down with hemorrhagic gastroenteritis or Dutch elm disease or something, so we played a prophylactic game of Xiangqi on boardgamearena just to be safe.
