A few years ago, I played in my first (and currently only) GURPS game. It was set in the early Age of Sail, using GURPS rules for tech levels where we had to find a new heir to the crown in Tudor-era England after an explosion kills Henry VIII. The game was, in predictable fashion for my group and the system, a little wacky: the leader of the sailing expedition had neglected to put points in either sailing, swimming or leadership. The doctor was a manic depressive pyromaniac (aboard a wooden ship). Our priest was actively planning to betray the party, and the rest of us learned it, leading to each trying to out-scheme each other. The game never finished, but for all the craziness, I still have fond memories of it.
