I've gotten myself into a game of Civilization this Saturday. (The board game, not the computer game, and also not the board game based on the computer game.) I've never played it, and I know very little about it. All I know is that I've got to block out the entirety of a Saturday for a single play, going from roughly noon to midnight.
(Correction: originally, I thought that I was going to be playing Advanced Civilization, but I was mistaken; it was the 1981 original.)
