Captain Park's Imaginary Polar Expedition is a scavenger-hunt board game. The board is a highly un-representational map of London, showing all the best places to find Artifacts, Photographs, Anecdotes, and whatever else you need to prove you've been to Africa, Everest or wherever. Just to make your life interesting, Captain Park is wandering around looking for you.
Once you've got some goodies, and you've been hiding long enough, you'll return to the Gentleman's Club to brag about your adventure. You'll score points for your stuff, bonus points for having different kinds of stuff, and more bonus points for being the first to go somewhere. If that's not enough, you'll also get a bonus if your destination just happens to be in style.
